摘要：
A security lock for doors of dwellings, gates and the like comprises a pump-type locking mechanism (8) for operating a bolt (2), and a double-bit locking mechanism (34) for locking the pump mechanism (8) in its locking condition. The lock preferably has both a key (10) which can operate only the pump mechanism (8) and a key (10, 10a, 10b) which can operate both mechanisms (8, 34). A cover (52) made of plastics material is associated with the key (10) and can be fitted onto the operative portion of the key (10) in order to protect its teeth (10a, 10b) against dirt and against the risk of breakage as a result of the key being dropped.
