PLASTIC STRING FASTENER HAVING DETACHABLE PARTS

摘要

In a preferred form, a string fastener made of a plastic molded material has two detachable and mutually interlocking parts for securing the end strands of a string. A base forming one of the parts includes a center opening. The other part forms a key having a stem connected in axial alignment with the center opening by a frangible membrane which is broken when the stem is inserted into the center opening. A tongue extending from the stem is guided into clamping engagement with the end strands along the center opening whereupon the base and the key are mutually interlocked.
