发明名称 JEWELRY CLUTCH
摘要 A method of forming a jewelry clutch includes the steps of molding an inner gripping piece from a substantially solid, elastomeric, thermoplastic material and forming a plastic outer casing having an opening at one end thereof around the gripping piece. The method further includes the step of inserting an elongated stud or post into the opening in the casing so that the post penetrates through the gripping piece to form a substantially resealable opening therein. The clutch formed by the method can be installed on the post or stud of a jewelry item so that the stud passes through the opening in the outer casing and is received in the resealable opening in the gripping piece to releasably retain the post in the clutch.
