I have a family member with a 37" Panasonic consumer plasma with a couple of HDMI connections. As the plasma warms up the HDMI cable eventually works itself loose and the signal is lost. I've looked at "port savers" however they look like they are nothing more than short cables. The cables themselves are not particularly heavy either.

Has anybody found a way to keep the male HDMI connection firmly in the female HDMI connection?
