Abstract: An open clamp structure, especially an earless clamp structure with overlapping inner and outer clamping band portions adapted to be mechanically interconnected; the clamp structure can be tightened about the object to be fastened by the application of a tighening tool at tool-engaging surfaces in these band portions; the tool-engaging surfaces are thereby so constructed and arranged that over-torquing during tightening is precluded. Savings in band material can be realized by the particular arrangement of the mechanical connection of the inner and outer band portions which also permits an efficient preassembly.

Abstract: A hose clip wherein a flexible annular strap can be place around one end portion of a hose and a relatively small portion (less than 50 percent) of the inner side of the strap is overlapped by the convex external surface of a deformable insert. The space between the insert and the strap confines one or more springs, or one or more springs are outwardly adjacent the strap, to bias the concave internal surface of the insert against the adjacent portion of the hose.
