ABSTRACT:
A locking device for telecommunications transceivers includes a key operated lock cylinder contained in a frame designed to fit between a transceiver's side mounted cradle and the opposed side of the transceiver's base, a latch bar attached to the lock cylinder and rotatable with the lock cylinder to engage the cradle in such a manner as the frame may not be removed, the frame acting as a wedge which holds the cradle down and keeps the transceiver electrically inactive.
