Abstract
An end fastener for attaching an end of an eyeglass retainer to the end of an eyeglass temple piece includes an elastomeric fastener body secured to the retainer cord or rope and having an internal bore extending into the body from an insertion opening. The diameter of the bore varies from a largest diameter near the insertion opening to a smallest diameter at the end of the bore away from the opening. A bulbous portion may be provided adjacent the opening and have the largest bore diameter therein. Because of the variety of bore diameters, the bore will receive and hold a wide variety of temple piece end sizes.
