Heavy power cord


I purchased a signal power cord... with it plugged into my SVS sub woofer  there's definitely a difference...
I can't seem to keep it plugged in due to its weight...any suggestion?

Based upon several ideas presented above I have decided that from now on all manufacturers of electronic components and power cord should incorporate a male “tab” on the IEC connection and power cord suppliers should have a corresponding female “tab” that locks on to the “tab” on the IEC. That would solve at least one part of the problem at the connection site. Cable elevators and other suspension devices will still be required by some who have heavy cords and need extra support but at least the cables will stay secured to the equipment. (Computer cables use locking connectors quite frequently). Comments?
Yeah, dream on. They ain't changing' nuttin.

Electrical heat shrink wrap will stay in place without adhesive making it better than tape. 

Ceramic cable elevators are primarily for improved sound. Try and see.
There is already a standard for this and readily available at least in Europe.

I have used Scotch brand, blue painters tape, around the female IEC end of a very heavy ac cable. Cut evenly, with a wrap around that was suitable for the particular connection. Never any gooey residue, if removed.....So, that I understand what I have thought for many years. The IEC plug end on pretty much every power cord, is the female, and the chassis mount IEC on the equipment, is the male, based on the plugs " blade " configuration. Somehow I thought this was stated above, to be opposite of this. BTW, I build my own cables, with excellent results.......
