Abstract

A key ring which includes a metal ring with an open segment area for the insertion and removal of keys has the metal ring mounted in a circular guide groove of a handle portion such that the ring is rotatable therein. A latch is slidably disposed in a passage in the handle portion and spring-biased into engagement with the metal ring for locking the metal ring to prevent its rotation. Means are provided for disengaging the latch so as to permit rotation of the metal ring.
