发明名称 Lock for ornamental jewelry chain
摘要 A simplified springless fastener includes a housing or box element onto which a first fastener element, having a clasp, is welded. The first fastener element has a hook-like extension extending into the housing. Insertable within the housing element is a resilient tang, having a second fastener element, which will engage, in locking fashion, the hook extension of the first fastener element located within the rectangular housing. The fastener elements may be unfastened simply by depressing one leg of the resilient tang. Thus structure is simple and economical to produce.
