Abstract: Paddle handle locks for securing push-pull, paddle-style door latches. In a first preferred embodiment the paddle handle lock is characterized by a handle lock having a frame with parallel side plates separated by spacers and fitted with a clamp arm pivotally attached to one of the spacers. Registering frame pilot holes and clamp arm pilot holes facilitate locking the clamp within the frame, such that the respective spacers prevent movement of the paddle door handle upon which the handle lock device is mounted. The padlock can be removed to allow pivotal extension of the clamp arm and manipulation of the door handle or removal of the handle lock from the door handle, to render the door latch operable. In another preferred embodiment a lockset handle lock is provided which includes a cylinder lock mounted in a lock housing and fitted with a pivoting clamp arm, one end of which clamp arm extends into the lock housing and engages a conventional cylinder bolt on the lock cylinder.
