Patent ID: 7322859

Claim:
An electrical connector comprising: a male part and a female part; a bayonet coupling between the male part and the female part; a spring-loaded locking pin projecting from one of the male part and the female part, and a slot in the other of the male part and the female part for receiving the locking pin, wherein the locking pin is received in the slot when the bayonet coupling is fully engaged, thereby to limit relative rotation between the male part and the female part and to prevent disconnection of the bayonet coupling while the locking pin is engaged in the slot, wherein the connector further comprises a sleeve surrounding an end of the part having the slot, the sleeve having a tab which projects into the slot, the sleeve being slidable to make the tab depress the locking pin against the spring bias of the locking pin, thereby to enable subsequent disconnection of the bayonet coupling.
