Abstract
A two-part fastener made of resilient material is disclosed as comprising two identical mating fastening devices. Each fastening device is constructed with a circular disc head integrally formed with a shank. The shank has an elongate symmetrically-shaped body having a longitudinal central axis and is formed with a pair of leg members disposed along the central axis in diametrically opposed spaced apart relation. Each leg member is formed by two wall elements molded together in a V-shaped configuration wth the outer end portion laterally spaced apart from the adjoining leg member a distance sufficient to embracingly receive the pair of leg members of the identical fastening device. When the identical fastening devices are brought together in a nesting relationship, they are locked together by virtue of the interlocking cooperating relationship of a plurality of tooth formations formed on one of the two V-shaped wall elements of each leg member.
