ABSTRACT:
There is disclosed a lock to prevent casual theft from dispensers. The lock includes a catch on one wall and a rotatable cam and a release spring with a latch on a second wall. The second wall has a bore for a key slot, an integral mounting post for the release spring, and integral mounting brackets for a retainer plate to hold the release spring and rotatable cam in position. The lock has a rotatable bore cover to inhibit operation of or damage to the lock. The cam is restricted in rotation and has cam profiles which cause the release spring to return to its closed position when the key is released.
