<p>In a swivel snap hook of synthetic resin, a unitary hook member (2) has a hook body (12) and a resiliently deformable closure tongue (13) molded integrally therewith, a free end (19) of the closure tongue (13) being, as the latter is in a free form, disposed inwardly of a free end (18) of the hook body (12) with a relatively small gap (14) therebetween. In use, as the closure tongue (13) is depressed inwardly against its resilience by a ring-shaped article to be threaded onto the hook body (12), the free end (19) of the closure tongue (13) is spaced wider from the free end (18) of the hook body (12) to open the latter. In production, the unitary hook member (2) is molded on a specific mold in such a state or condition that the free end (19) of the closure tongue (13) is disposed inwardly of the free end (18) of the hook body (12) with the small gap (14) therebetween.</p> |
