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.
