ABSTRACT:
One or more radially projecting tabs are provided on a discontinuous ring for retaining the ring in proper association with a body member in spite of movement or vibration of the assembly. The tab, or tabs, mate with a grooved section of the body member. The groove may comprise a thread. The ring may be internal or external to the body member. The retaining tab will project radially outward or inward when the ring is to be internal or external, respectively, to the body member. The tabs have an axial thickness of the order of 25 percent, or less that of the ring. To provide secondary internal retaining means, a portion of the ring may be cut from an oversize ring so that a stress is formed when the ring is closed for inserting the ring in an internal opening. When a ring is to be used external to a body member, a simple cut may be made in an undersize ring so that a stress is formed when the ring is opened for placement external to the body member. The ring may be fabricated from any suitable material including: metal, plastic, or an elastomeric material. When the ring is made of appropriate material and cut at an appropriate angle, it may be used as a seal.
