ABSTRACT:
An apparatus secured to a framework of a sliding window or door framework to receive a frame flange therewithin and provide an abutment plate to effect abutment and prevent unwarranted opening of a sliding framework relative to the fixed framework. The rigid body includes a slot to receive the framework flange therewithin, with an abutment flange mounted to a top wall of the body providing abutment for the framework slidably mounted relative to the fixed framework. A modification of the invention includes a plurality of rigid bodies mounting an abutment housing, with the abutment housing including an actuator rod displaceable relative to the abutment housing to effect actuation of a signal member defined as an inflation balloon upon deflection of the actuator rod relative to the housing.
