Abstract: The invention relates to a clip made of plastic, in one piece, consisting of two articulated arms (1,2), one of the ends (4) of which serves as jaws and the other end (5) as a lever arm, and of an upper elastic component (10) forming a spring, which comprises, between the two arms (1,2) and the elastic component (10), two swivelling, crescent-shaped components (8,9) for opening and closing the clip, which are united by a hinge (11) and joined both to the ends (5) and to the elastic component (10) by two groups of corresponding hinges (6,7,12,13).

Abstract: The disclosure relates to a resilient friction clip adapted to be received over and to frictionally grip the wire portion of a merchandise display hook, such as used pegboard displays. The clip is formed of resilient material, of extruded, or more preferably molded construction. A center aperture is provided for gripping the wire, and a radial slit extends from the periphery of the clip into the center aperture, enabling the clip to be forcibly applied over the wire. A pair of angularly disposed manipulating tabs are formed integrally on the clip, opposite to and symmetrical with the radial slit. The manipulating tabs may be gripped by the fingers and squeezed together, to open the radial slit and greatly facilitate application of the clip onto the wire. Squeezing of the manipulating tab also tends to release the friction grip of the clip on the wire for easy adjustment of its position.

Abstract: A clamp useful for connecting fluid-conveying hoses and the like to couplings, valves and the like. The clamp is formed of a spring metal strip which has portions of its longitudinal parallel linear edges cut to provide a pair of parallel inclined linear edges such that the original constant width of the strip is gradually reduced toward the longitudinal opposite ends of the strip so that the width of the strip varies in proportion to the bending moment produced in the strip, with the thus narrowed opposite ends being bent in mutually opposed relation to provide operating knobs for forcibly spreading the ring diameter. The spring metal strip thus prepared is then wound into a ring of right circle, with the inclined linear edges abutting against each other along a given length, thereby ensuring uniform bending stress throughout the ring.
