loose IEC power cord connection?

Recently read a comment about power cords not "ever" fitting tightly to the component. I certainly experience this especially with stiff/heavy PC's. Any thoughts on this or recommendations?
You may need some cable holders or elevators to keep the heavy or/and stiff power cord in place. I have two power cords like that and use improvised elevators. Unless things are really loose because either IEC is too big or power cord's plug too small by design, it should work.
I have used wood blocks under the bottoms of heavy A/C powercords. Or butyl rubber bottle stoppers.
Anso, (but messy) BluTack rolled out and pressed around the mating outer edge of the connection.
The messy part is when it it pulled apart. The Blutack stretches and is gooey.
I find I can clean it up using the Blutack to pick up itself until all is removed. Annoying but i do use Blutack like (cheap) stuff for antivibration control.

I also wrap the Female cord end of the IEC with Teflon plumbers' tape. About five or so turns makes the connection tight. (naturally if loose more, if already too tight, fewer)
Every one of my powercords also has the teflon tape on them.
I have improvised pc support using toilet tissue tubes. Cut a u shaped slot at one end, slip under the plug or IEC. Adjust
slot height to fit.
I move the components to a lower shelve on my racks so it doesn't hang as much and fall out.
Audio Research resisted using IEC sockets for years for this very reason. There is no better connection than a hard wired power cord.
thanks to all. I'll try the recommendations.
It's not so much a question of the IEC connector fitting into the component. It's whether the connector grips firmly onto the component's prongs. Many connectors fall right back out and if that happens, no wrapping, etc. of ends is going to help make a firm electrical connection. This is the main reason I use Furutech IEC connectors when possible. They really grip.
Rrog, agree with you.

My Conrad Johnsons ART preamps (at least the series 2 and 3) came with hardwired cords. At 16,000 and 25,000 dollars, I don't think they were trying to save a few dollars by doing that. At least they have hospitol grade plugs on them.
If anyone is concerned about the lack of contact inside the IEC female plug, One can insert strips of material under the metal inside the plug.
So the metal box in the female plug is slightly pushed in (mainly near each center face) so the plug makes a more solid contact.
It may also make the plug much harder to push in.
I would use stiff paper, rather than wire, just to keep the chance of a loose wire coming out from under the sleeve and shorting the plug.
Best method I found was fitting a piece of black heat-shrink tubing over the IEC plug.
Black "electricians" tape is all you need. It's so bloody easy...just wrap a couple turns.
Nothing applied to the outside of the IEC plug does a thing to improve its connectivity. Just keeps it from falling out.
I think not falling out would help the connectivity everytime;^]
If one looki=s into the A/C connection from a wall receptical to an A/C plug.. One can see the connection between the two parts is a rather small area of contact.
The IEC connection is a rather large area of contact, as much as twenty times the area of contact. So.. if it is not making solid contact over 80% of the surface, it STILL is a better connection than a standard American A/C connection.
Okay, but put a Furutech IEC connector on your power cord and I'll bet you can hear the difference :-)

This is assuming that you can do this without miswiring, electrocuting yourself, burning the place down, or otherwise wishing you hadn't.
