Metal clasp

Abstract

A metal clasp includes an outer housing made of a sheet of metal foil folded about its notched center portion so as to define a generally U-shaped housing having two opposed surface portions defining lateral openings therebetween. The clasp additionally includes a generally C-shaped element having two arched portions, one of which terminates in a flat end which is normally disposed to the axis of the element and the other of which terminates in a bevelled end which is obliquely directed towards the center of curvature of the associated arched portion. This C-shaped element is mounted in one lateral opening defined between the two surface portions of the housing and an elongated latching bar is introduced into the other lateral opening thereof. The latching bar is pivotably supported at one end and has an opposite free end which terminates in an oblique surface complementing the bevelled end of the other arched portion. The latching bar is spring-loaded so that the oblique surface thereof is urged against the bevelled surface of the arched portion to thereby substantially close the opening between the ends of the C-shaped element.
