CA 2370870
The invention is directed to a device to protect a deadbolt assembly from tampering. A deadbolt assembly comprising a deadbolt reciprocable along a longitudinal axis, and a deadbolt actuating mechanism having an axis transverse to that of the deadbolt, is protected from intrusion and tampering by a pair of protective shells which ~ the actuating mechanism. The shells are generally cylindrical and of like structure and opposite orientation. Each shell comprises a ring and a circumferentially extending protective structure which extends axially toward the ring of the other shell. A preferred protective structure comprises a plurality of projections, including an arcuate tongue. A gap or opening in the protective structure permits actuation and movement of the deadbolt without interference with the shells.
