Pipe clamp (clamping collar) consisting of a band (1) of material, in general a metal, wound up on itself, one of the ends of the said band having reliefs forming a rack (1b), whereas on the other end, is fixed a tab (2) which constitutes the support for a screw (4) which is mounted therein so that it can pivot about its axis, the said screw bearing on a stop piece which can move axially with respect to the tab against the action of a spring. The spring consists of a curved blade (3), for example in the shape of a semicircle, the concavity of which points towards the inside of the clamp and the ends (3a) and (3c) of which are laterally in contact with the flanks (2b) of the tab. A first end (3a) of the said blade is axially fixed to the tab and provided with an opening (3e) in which the tail (tip) (4a) of the screw can slide, whereas the second end (3c) of the blade at least partially surrounds the shank (4b) of the screw in the vicinity of its head (4c) and is mounted so that it can slide with respect to the flanks (2b) of the tab. <IMAGE> |
