Abstract: A clip for attaching a fishing lure or hook to a fishing line comprises an elongate body having a central support member bridging first and second loop portions formed at respective proximal and distal ends of the clip. The support member has a shoulder intermediate its length which reduces the width of the clip near its distal end. The first loop portion is adapted to open, and includes an arm member having a first end connected to the support member through a bend at one end of the clip, and a U-shaped hook member connected to a second end of the arm member. In the open configuration of the clip, the U-shaped hook member is disengaged from the remainder of the clip, and in its closed configuration, the U-shaped hook member is received around the support member at a point distal to the shoulder, such that the presence of the shoulder effectively reduces the displacement of the arm between its open and closed configurations, thereby reducing fatiguing of the metal comprising the clip.

Abstract: The invention relates to a hook for hanging ornaments on a Christmas tree and is equally useful as an article supporting hook for lightweight objects such as necklaces, keychains, laminated cards and the like. The hook is provided with an article supporting portion and an integral circular portion with a depending locking leg portion. In use the hook is placed over a supporting member such as the twig of a tree as a supporting rod with the twig or rod inserted through an open portion of the circular portion. Then the locking leg is manually manipulated such that the horizontal portion of the locking leg is retained behind an upper portion of the article supporting portion and due to the resiliency of the hook the locking leg is continually closed. To release the hook from the supporting member the locking member is manipulated such that the locking leg is released from the upper portion of the article supporting portion permitting the hook to be removed therefrom.

Abstract: A fastener for jewelry and the like comprises a box-shaped structure made of foil and has, at both ends, two transverse seats which receive fastening elements of a chain or the like to which the fastener is attached. One end is formed by a half-open hook which is closed by a resiliently mounted tongue forming part of the box-shaped structure. The tongue is shaped to increase its stiffness so that the fastener will not become unfastened accidentally despite the fact that the foil is of soft metal such as gold.
