Here's a trick I learned while working construction.
If you plug two extension cords together like this, they won't come unplugged by accident.
When you're done they're easy to unplug.

    wow this is awesome, EXACTLY what I needed to know I am so grateful u posted this

    thank u!!!!

    Take both lines and hold them side by side about a foot away from the plugs then tie a knot in the cord made from two side by side cords...

    oo oo i know, my dad showed me along time ago, but i forgot... but i remember that all u gotta do to untangle it is pull, and the whole thing gets undone =D

    It's basically just a crochet chain with the cord.

    its called a carpenters knot

    When you are coiling it, you switch off on which side you put new loops on. When you uncoil, the wire/cable will lay flat and not kink up on itself.

    i always use this, but ill try it with the extra twists next time....

    This 'ible very much needed to be published.

    I once went to a hardware store, and they had these little boxes that you clipped over the ends of the cords that stayed on permanent. Then, when you plugged in the cable, you slipped the boxes over the ends and they made a satisfying click together.


    I spent a good 10 minutes just laughing at this product, and couldn't comprehend what fool would spend his money on something that takes at most 15 seconds to just tie the cable ends in what you have pictured here.

    The boxes were not waterproof. They were not particularly well secured either, as it had to be a 'one size fits all' product, so I can imagine the cables coming unplugged INSIDE the box if you tugged hard enough. It was not crush resistant. It didn't even look like it was that well made.

    thanks for this good reminder. Not only do plug want to unplug, they tend to ground out if the ground may be damp. We get busy working on projects and forget about the limit of the cord.

    Actually the best way is to hold the ends of both cords and tie a figure 8 or flemish bend knot. That will take the stress off of the ends in case the cords are pulled tight

    Takes stress off the ends at the expense of adding stress to your cord though.

    no the best way to do it is splice the cords together, add nylon fibers to the splice and dip it in a vaut of molten orange plasic. this way it easier, it takes up less cord and less "weight"

    If you want a permanent fix, yeah..., but this 'ible ain't about permanent joins.

    Hi Tim, glad to have your news!

    I just saw this. I put it up also. My Dad is a carpenter and taught me to do this.

    i use it all the time when i have a drill or sumthing that won't stay pluged into a extension cord...awesome trick tho


    tell me more about this "counter coil" please!

    I love that, I am going to use that for my USB extention cord
