ABSTRACT:
A key retention system for electrical connectors which includes a connector (12) including a lower backshell (42) having at least one generally T-shaped slot (51) extending therein from a side face (52) thereof for receiving a generally T-shaped key (61). Slot (51) and key (61) are configured to permit key (61) to be easily inserted into slot (51) in the correct orientation and to prevent key (61) from rotating or from moving laterally or longitudinally within slot (51) to any appreciable extent. Locking means comprising a projection (81) extending inwardly from the cover (43) for the lower backshell (42) is positioned to extend into the slot when cover (43) is mounted to lower backshell (42) to lock key (61) in position within slot (51).
