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.
