The clamping collar consists of a first part (10) of the metal band folded round itself, called the interior part, having in the neighbourhood of one (10a) of its ends, a radial double fold (16) termed the ear, and by a second part of the band (12) called the exterior part, which is fixed to its first end (12a), onto the external face of the interior part (10), this having an undulation (20) forming an elastic reserve. It is provided at its other end with a hook (18) which clips behind the ear (16) when the collar is clamped up. The intermediate part (22) joins the two parts up. It is characterised in that it has a first (32a) and a second (34) stop, fitted respectively on the intermediary part (22) of the exterior part (12) and on the covered zone (24) of the interior part (10) which are so designed to cooperate one with the other for determining the limit of use of the elastic reserve. |
