The receptacle extends along a longitudinal axis and includes a pair of parallel extending spiral raceways formed in the inner surface of a central opening that extends therethrough, and a keyway formed adjacent its terminus. The bayonet assembly includes a pair of bayonets that are adapted to ride in the raceways and a key positioned at the end of a plunger and is adapted to engage the keyway thereby locking the bayonet assembly in the receptacle. The locking assembly includes the plunger that when manipulated by a tool either engages or disengages the key from the keyway.
