loose power cord

[cptnhook]

I'm having issues with the connection between my power cords and my power amps. I'm talking about the power cords that have three slits at the end of the jack, the same ones that are used with computers and other devices. We transport our gear back and forth every week, and the power cords come unplugged from time to time. Are there any products for keeping the cords plugged in?

Thanks

Duct tape is the first thing that comes to mind.... sry.
If they are getting loose with age, try some vinyl electrical tape- wrap around the outside of the plug a few times, that should tighten the connection temporarily, while you have time to replace the cables.

I did a search, the best key words that got close to what you are looking for is "strain relief" maybe you have the time to look.
