ABSTRACT:
An elongated separable fastener includes two similar sections formed of a resilient resin, each section including a longitudinally extending socket with a restricted throat and an elongated plug with an enlarged head which releasably engages the socket of the other section. Mating transverse recesses and projections are provided in the fastener sections to restrict their relative longitudinal displacement. In one form, each section includes a base web and a pair of transversely spaced longitudinal vertical plugs and longitudinally spaced projections projecting medially from the web, the space between one of the plugs and the projections defining a socket, and in another form, each section is U-shaped with enlarged heads on the side legs, longitudinally spaced transverse ribs being positioned at the base of the socket between the legs and the legs having longitudinally spaced transverse grooves. A plurality of side-by-side sections may be integrally formed as well as back-to-back sections and they may be longitudinally reinforced.
