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?
Thanks

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.
