Abstract
A key controlled lock mechanism for locking one or more sliders of a zipper fastener, wherein the lock member is of circular disc-like configuration having a cup-shaped cylindrical casing and a rear backing plate assembled together with a circular latch plate rotatable through an arc therebetween. The latch plate has a latch tongue and a recess receiving a key operated locking disc journaled in the casing and shaped to selectively lock or release the latch plate. Various forms of keepers are disclosed to be mounted on a receptacle closed by the zipper fastener or to be coupled with the pull tab of the zipper slider or formed by special shaping of the slider.
