ABSTRACT:
A retaining ring for use with a fastener is disclosed. The retaining ring comprises a plurality of substantially t-shaped internal tabs that oppose one another and are about twice as thick as the exterior of the ring. The ring is installed onto a fastener having at least two longitudinally-oriented slots by locating a tab into one of the slots and snapping another tab into another slot, thereby momentarily elongating during installation. The tabs substantially reduce the possibility of accidental removal of the retaining ring. In addition, resistance and damage to the internal tabs of the retaining ring is substantially reduced when the retaining ring slides axially in the longitudinal slots of the fastener. Since only the longitudinally-oriented slots are required for installation, the axially-oriented entry slots and cross-over slots of some fastener embodiments can be eliminated, thereby significantly reducing fastener cost and manufacturing time.
