ac cables falling out of IEC inlets on amps


I use medium weight power cables with Marinco connectors.They sound good, but they fit in the IEC inlets on my monoblocks only loosely and can easily loose their connection. I am considering replacing the inlets on the amps with ones that solidly grip the powercord.
Any suggestions?

Drubin is right. The idea of "gluing" the cord to the chassis, with real Blu-Tack, or the generic stuff from Office Depot, doesn't appeal to me, for the reasons stated by Jeff_jones.
I use a mechanical solution where it's feasible -- I support the power cord plugs with small wood blocks under them so they stay in place.
I've often thought the connectors should be held in place with screws, like serial cables on computers. I'm sure I'm not the only genius out there.

Dave, Thanks for the link. Looks like an elegant solution. Does anybody know how well they work?

What would be great is a holder that could be used with existing IECs without requiring opening equipment and removal/replacement. Why can't a holding clip like the one pictured be installed on any IEC that screws in (as opposed to the (minority) press-in-place ones?

The retaining wire and two longer screws shouldn't cost more than 125 audiophile dollars. Some enterprising soul could make a fortune and earn fame and the undying gratitude of millions (or at least thousands).

Power cord manufacturers could supply them with each power cord.

OK, brainstorming here but you get the idea.

Drubin, I share your frustration and wish there was an easy way to change the "standards". It is not just the IEC end. I am not happy with the wall end of things either.
It seems to me one solution would lie in the design of the inlet prongs.A possibility would be to spring load them by shaping each prong to be effectively a leaf spring.Easy.
Try to use cable ties to suspend the cable above the component so the weight of the cable is not pulling down the IEC connection.
On the other end, I have even gone as far as attaching L brackets to the wall above the wall outlet to be able to hang cable ties to support the weight of a heavy plug .
