Abstract
A locking device having a cylindrical plunger with a key thereon and a cylindrical sleeve for receiving the plunger and key. The sleeve has a lip therein with a mating keyway that passes therethrough. An indicium on the sleeve is aligned with the keyway. To lock the device the plunger is inserted into the sleeve, the key sliding along the keyway through the lip into the bottom portion compressing a spring member therein. The sleeve and plunger are then rotated with respect to each other and released, the spring biasing the plunger upward to lock the key onto the bottom surface of the lip. To unlock the device, the sleeve and plunger are pressed together and rotated with respect to each other until, by noting the position of the known indicium, the key and keyway are aligned with each other. The plunger is then removed from the sleeve.
