ABSTRACT:
A fastening device comprising a curved clamping plate bent into shape from an elongated, resilient plate which has an elongated slot longitudinally disposed at one end, a square recess spaced from said elongated slot and a hole disposed at an opposite end for holding a key chain; and a substantially Z-shaped strip spring having one end fixedly secured to said elongated slot at one end through welding joint before said elongated, resilient plate being bent into shape. The strip spring is squeezed to produce a spring force, when the curved clamping plate is clamped on an object, to rub said object against the square recess so as to firmly retain said object therebetween.
