ABSTRACT:
A releasable clasp including a male insert member and a female receiving member, the female receiving member including a passageway having a single retaining slot in one wall. An abutment projects into the passageway from an opposing wall. The male insert member includes a body portion supporting a pair of forwardly directed springy arms which are insertable into the passageway. One of the arms serves as a guiding arm, and includes a nose portion and an inwardly stepped surface longitudinally extending rearwardly from the nose portion and terminating in a shoulder. The other arm serves as a locking arm, and includes a locking tab for entry into the retaining slot. Teh nose portion is spaced forward of and overlaps the locking tab. Upon entry of the arms into the passageway, the shoulder causes deflection of the guiding arm toward the locking arm until further inspection brings about the entry of the locking tab into the retaining slot. The male insert member can be fully inserted in only one orientation into the passageway. The abutment prevents full insertion into the passageway when attempting to insert the male insert member in an incorrect orientation.
