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. The invention also relates to the clamping collars thus obtained and a method of locking a collar in clamped position which consists in bending the strap portion emerging from the shell just beyond the latter, utilizing the space formed as a result of the fixation of the strap under the collar shell. |
