Designed to prevent annoying extension cord disconnects in the shop, the E-Zee lock adaptor snaps over power connections, holding them together better (and safer) than your own homemade tape or safety wire solution.

It works by attaching a nylon bracket behind the plug of both the male and female ends. Ther’s a collar at either end of the adaptor that keeps the plugs in place, preventing someone’s clumsiness from disconnecting your tool.

It’s an easy $7 way to solve an annoying disconnecting issue, but is this a problem you really want to solve?  If you don’t remember to leave a few feet of spare, coiled extention cord and someone trips on it, the plug will come out of the wall or they’ll yank the tool out of your hand.

On the other hand, this might be just the thing for a “middle” extension cord, assuming you still have a “breakable” connection near the tool.  Of course, are you killing your tools slowly by hooking that many cords together?

Is this a worksite must have or a worksite hazard? Let us know what you think in comments.

    Not – I always just wrap the extension around the other cord forming a loop and then plugging them together. If you pull, you just tighten the loop. Granted, it does not solve the problem of pulling it out of the wall, but I don’t see this resolving that issue either. My method is also really fast to disconnect, whereas this does not look so fast or easy.

    I’m in the process of redoing my shop and the first step was to add an outlet every 4′. Eliminates extension cords completely for about $150 and everything is 20A, so no need to worry about insufficient power or extension cord gauge.

    I’m with KB. I use the exact same technique. Just take the two cords and make a minor loop at the connection. When they get pulled apart, the loop tightens. And it works with all guages of extension cords. I’ll have to go with ‘NOT’ on this dedicated piece of gear.

    What a waste of money! I too use the “loop” method, that was the first thing my father taught me about power tools. I can definitely list a MILLION things that 7.50 would be better spent on that that.

  4. Steve Thompson says:

    Me too. Nothing wrong with a loose knot. And there’s 7 bucks left over for beers.

  5. John Eisenhower says:

    I use the knot method instead of a loop. It gets rid of extra slack if need be and you can hang it by inserting nail/branch/etc into the middle of the knot.

  6. Mark says:

    NOT. By the way, I thought your are not supposed to put too much force on the cord part of molded plugs. How many people who care about their tools will yank on the cord to pull out the plug? I’m certainly not going to hang a worm-drive circular saw from its plug …

  7. Fletcher says:

    Another nod to the knot.

    Add me to the “knot the extensions cords” crowd.
    And just to make sure we’re all talking aboiut the same thing, here’s a picture of what I mean.

  9. Clinton says:

    Personally I wrap the cords more than once before plugging them. The extra wraps helps reduce the lateral deflection on the connectors should they be pulled on. With heavy gauge extension cords it’s not really an issue because the stiffness of the cord helps avoid the issue but I’ve seen several plugs mangled by using the single-twist knot with lighter gauge extension cords. I had to graft a new plug onto my shop light after my brother knotted the cord and when it pulled tight the plug pulled to the side and it broke one of the prongs off.

    I got an octopus type outlet multiplier that uses this type of lock. Forgot about the lock and was reaching for a screwdriver to pry the plug apart; this after a good kinetic workout trying to pull the thing apart. The only benefit I could see is it makes a good tight electrical connection. I didn’t get it for the lock, I got it so I could plug in multiple wall warts and not cover up outlets.

    Buy the beer not the lock!

  12. David says:

    Maybe this would be better if it were like a fusible link and melted if the plug overheated – that was always why people told me not to knot the cords, that if there was a problem you couldn’t undo it fast enough.

  13. Kurt Schwind says:

    Browse, that is exactly the loop/knot I was referring to. Nice pic.

  14. Leslie says:

    I clicked comments feeling quite puzzled that anyone would need anything beyond a loop knot, such as the one that y’all are using and that was in the picture posted. This is definitely a useless gadget that would find its way into the bottom of the tool box, or pitched out.

  15. TarHeel478 says:

    We’ve used this for some time now and I think it works great. My father also taught me the ‘knot’ method. However, I learned later on that wrapping a cord casuses kinks in the cable, which caused friction adn reduced the flow of electricity, therby hurting my tool (like using a 13amp cord with a 15amp tool). It took our guys a few times to get the mechanism down, but it’s like second nature now.

    We dont use it to store tools, but it does prevent plugs from exposing live contacts. When a tool is dropped, the lock comes apart but can be easily put back together (one of our guys dropped a saw of the roof, and this came apart so the cable wouldnt take him down also).

    Overall, I think this is a good tool with a short learning curve.

    This product is a must if your a serious user of power tools. It connects and disconects with just flipping the plastic lever. Your extenion and power tool cord will last longer and you’ll have less interruptions from the connection coming apart. Tying your cords in a loop or not creates more stress on the cord ends, causing the ends to pull away from the cord. You then have to throw the cord away or spend money buying replacement ends. Incidently, once you replave the ends, the cord is no longer a UL approved product. If you are working on a commercial job site OSHA inspectors will cut your cord in half.

  17. OC5382 says:

    This is a great product! Tying your cords in knots reduces the flow of electricity and can be very dangerous in a serious working enviornment. It does not add as much cost to a cord as many have previously stated. I have seen regular cords in stores and i have seen Voltec’s E-Z lock cord, the price difference is very insignificant when compared to the advantages. The E-Z Lock makes cords very clean on a worksite and you dont have a bunch a cords, tied in knots, sitting around the construction site.

  18. Raistlin says:

    Just bought a leaf blower/vac and the cord from tool is very short. I plugged in my 100′ heavy duty ext cord and the plug is unfortunately not a tight fit and easily . Cord from tool is so darn close to tool that I had a hard time making a knot so something like this would be pefect for this situation.
