Interconnection retention device
 A compressible retention element of a diameter slightly greater than that of a cooperating cavity, having a low ratio of insertion to withdrawal forces. The retention element further provides insertion and withdrawal forces reduced from that found in the prior art. One embodiment of the retention element includes a cylindrical body, manufactured of a pliant material such as plastic or the like, having a wedge-shaped groove disposed axially along its length on one side and a planar region disposed axially along its length on an opposite side.
