Abstract: A locking device for securing a gate so as to prevent tampering to the locking engagement of said locking device is provided. The locking device may include a lock latch which slides into a housing for forming the locking engagement therein. The cavity formed by the housing is accessible through a sliding door that encases the cavity and so prevents tampering to the locking engagement. The slide door forms a blade notch that a lock blade may engage, wherein the lock blade is key-actuated through the bottom wall of the housing.
