ABSTRACT:
A device (70) is provided for a pair of clip lock connectors (12, 14), wherein the device can be slid forward (F) from a release position to a locked position, only when the connectors are fully mated, and which then prevents connector unmating unless the device is slid back to its release position. The device has a pair of bars (80) which, in the release position, lie rearward of spring sides (24, 26) of a spring clip (20). During initial mating of the connectors, the spring sides block forward movement of the bars. When full connector mating is reached and the spring sides snap into slots, the device can be slid forward to its locked position and the bars lie immediately outside the spring sides. The device has deflectable arms (92, 110) and is initially held in its release position by a wall (102) on an arm projection (90), which lies behind a barrier (94). As the connectors mate, a cam (96) on the second connector engages a cam follower (106) on the arm projection to deflect it so the wall disengages the barrier and the device can be slid forwardly to its locked position.
