Abstract: Method of assembly of the shell with the strap of a clamping collar, and collars obtained with this method.This method consists in fixing the strap under the shell of the collar and no longer by passage inside the latter. With this in mind the shell (7) has, in the part forming its base (8), cut-outs preferably forming two tongues provided between remaining parts of the base. These tongues are cranked and the shell is fitted over the strap in a straddling position. The tongues are then flattened, the force applied preferably causing the corresponding strap portion (2) to penetrate by bending into the opening thus formed in the base of the shell. A non-slip bond is obtained between the shell and the strap owing to raised parts of the strap penetrating into the cut-out or opening in the base of the shell and forming immobilization stops.

Abstract: An "open" type clamp constituted by a wound over metal strip 1, comprising two radial folds or ears 2-5, whereas a first ear is bent over and is provided with an extension directed along the periphery of the clamp to constitute a sole 4 which extends substantially over the distance separating the two ears. The second ear 5 has an extension 6 which is substantially parallel to the periphery of the clamp and extends as far as close to the first ear 2, comprising at its end a portion 7 bent towards the clamp.
