  • Patent number: 5063765
    Abstract: A lock protector (1) for the barrel (17) of a key operated lock (2) which comprises a sleeve (3) to fit over the barrel (17). The sleeve (3) has a rotatable keyway protector (7) located adjacent the keyway (6) of the lock (2), the keyway protector (7) having a slot (10) therein which aligns itself with the keyway (6) for use. The width of the slot (10) together with the distance between the external portion of the slot (10) and the keyway (6) prevents objects other than the correct key shank from being inserted within. The lock protector (1) is also provided with a retaining means (4) to prevent longitudinal movement of the barrel (17) within the sleeve (3) once assembled.
