  • Patent number: 4079607
    Abstract: A ring member comprised of a generally flat body section and a ring section defining a substantially closed loop at one end thereof is closely slidably received within a hollow open ended slide member. Spring biasing means are received in an elongated slot in the ring member body section with one end of the spring operating against one end of the slot and the other end operating against a tab member which comprises a part of the slide member. The spring continuously urges the slide member to a first normal position blocking an opening in the substantially closed loop of the ring section and also allows selective movement between the ring and slide members so as to expose the loop opening. A decorative outer cover closely surrounds the slide member. The slide member and outer covering include cooperating means for retaining the cover in position on the slide.
