  • Patent number: 4639983
    Abstract: A hook for a hook-and-eye fastener includes a one-piece hook body having at least one pair of prongs, and a retainer having openings through which the prongs extend, respectively. The hook body includes a locking tongue and a base underlying the locking tongue, and an arcuate portion joining the locking tongue and the base, the prongs projecting substantially perpendicularly from the base in a direction away from the locking tongue. The hook body has a plurality of cold-pressed elongated recesses defined in an inner surface of the hook body and extending from the base through the arcuate portion to the locking tongue, thereby giving resilience and strength that are large enough to withstand forces tending to permanently deform the hook body at the arcuate portion. The openings in the retainer are spaced from one another by a distance which is larger than the distance between the prongs. Each of the prongs has a bent end portion retained on the retainer with a space defined therebetween.
