Abstract: In accordance with the process of the present invention the flexible collar of a screw-type clamping collar is formed of a flexible metal strip of predetermined width, and one end thereof is either hot or cold stamped to force material of the collar outwardly along its edges at predetermined locations where transverse shoulders are desired to serve as stops for the clamp's saddle housing with sufficient rigidity and strength to withstand the pulling force applied to the clamping collar.

Abstract: A screw-type clamping collar includes a flexible band having first and second end portions and inner and outer surfaces with a rack of teeth formed in said first end portion and having a part thereof protruding inwardly of the inner surface of the flexible band, on the side of the parts to be clamped. The second end portion of the band has a screw bearing saddle housing rigidly connected to it, and an axial opening formed therein having a width corresponding substantially to the width of the protrusions. These protrusions are engaged and maintained transversely in the opening of the band over a length corresponding approximately to the length of the housing and of the screw to guide movement of the band beneath the screw.
