Sort of like the other mention of it... I'd add some layers of heat shrink, one at a time until the fitting was snug.
Of course, that's not helping the contacts get tighter but will help the cords from pulling loose.... also, I use plain old string to trace up the heavier cords to the rack itself... thereby taking the strain off the connection.
