ABSTRACT:
A cable release and latch for a security guard hinged to a window or the like has a spring loaded plunger swedged into an outer frame thereof. An armored cable with a flexible inner cable is connected to the spring loaded plunger and extends to a foot treadle operator and shield which may be mounted on the floor inside the opening. Sufficient length of cable is provided to allow free movement of the guard about its hinges. The security guard may thereby be quickly and easily opened without a key by stepping on the foot treadle operator. If the armored cable is severed, the spring loaded plunger advances further into the keeper which retracts the flexible cable within the armored housing to prevent the manual operation of the latch without further dismantling of the cable.
