Claim 1

A clip comprising a single body of synthetic resinous plastic material consisting of two opposed elongated members and a bridge piece locally uniting the members intermediately along the lengths thereof to serve as a fulcrum, two adjacent ends of the members being finger grips and the other end parts of the members being jaws, the bridge piece having a concave arcuate face merging into the opposing faces of the finger grips, and a generally V-shape leaf spring located between the finger grips with the apex of the V-shape adjacent that arcuate face and the limbs of the V-shape spring extending in engagement with said opposing faces to force the finger grips apart and thereby rock the members in opposite senses about the bridge piece, as the fulcrum, to force the jaws into mutual engagement, wherein said concave arcuate face of the bridge piece extends through more than 180* to form a reentrant recess with inturned extremities the apex of the V-shape spring is a loop which is arcuate through more than 180* and of diameter greater than the gap between, and defined by, the extremities of the reentrant recess, the loop is positioned within the reentrant recess with the limbs of the Vshape spring extending therefrom through the gap, and the finger grips are formed in said opposed faces thereof with longitudinal channels extending, away from the bridge piece, beyond the ends of the limbs of the spring which extend in the channels.
