ABSTRACT:
A security device for a door structure comprises a simple bracket that surrounds the retractable latch element at the edge of the door, the bracket having a return extending along the inside of the door, stopping short of the inside latch or lock actuator. A resilient pad is interposed between the return and the door. The bracket is connected to the latch element, either directly or indirectly upon imposition of a break in force so that, immediately upon imposition of a kick force adjacent the lock, the latch element engages the bracket, thus transmitting the force to the inside return, and through the shock absorber to the inside part of the edge frame member.
