Abstract

An apparatus for generating a remote alert signal in a communication receiver, the apparatus includes a remote alerting device, a latching receptacle enclosed within a casing of the receiver, and an electrical connector cable. The latching receptacle includes a socket accessible from outside the casing and a locking means comprised of a resilient means and an actuating means. The connector cable terminates at one end with the alerting device and at the other end with an electrical connector in the form of a mating plug having a groove extending around the periphery of the plug. The mating plug inserts into the socket and the resilient means being normally biased into the groove prevents disengagement of the mating plug. To release the plug, the actuating means forces the resilient means out of said groove to permit the mating plug to separate from the socket. The connector cable provides electrical communication between the receiver and the alert device. Additionally, the combination of the groove and resilient means allows the mating plug to be rotatable to prevent twisting in the connector cable.
