Abstract: An end fastener for attaching the end of an eyeglass holder cord to a temple leg of eyeglasses, said end fastener comprising a body of elastomeric material having an elongated tubular shape and a hollow core, including a base and at least one open end, and having a long axis defined through said base and said open end, said axis running through the center of said hollow core, said open end being adapted to receive a temple leg of eyeglasses, said base having means for connecting said body at said base to said end of a holder cord, said means for connecting comprising a hole extending completely through said body substantially orthogonally to said axis in the region of said base.

Abstract: An improved end fastener for attaching the end of an eyeglass-holder cord to a temple leg of eyeglasses includes an elongated elastomeric body having a double-tapered slot for resiliently mounting the body about a temple leg. The slot has a slotted narrow web at the narrowest location. A hole in the body holds a connector ring to connect the body to an end of the holder cord via an eyelet of a cord-end cap. Molding of the double-tapered slot includes use of two opposed, tapered cores, each disposed in a half-cavity of the mold.
