L'invention concerne un raccord de canalisation comprenant deux embouts et un collier à chaîne serré sur les embouts. Les maillons du collier à chaîne sont reliés par un ressort en forme de C qui confère au collier une structure semi-rigide, et un jeu longitudinal par rapport au ressort est défini entre ce dernier et chacun des maillons afin d'empêcher la transmission au ressort des efforts de serrage. Application notamment aux raccords devant être manipulés à distance. (CF DESSIN DANS BOPI) Pipe coupling of the type comprising two end fittings which can be fixed to two parts of the circuit to be connected and an open collar constituted by a plurality of articulated elements, with which are associated tensioning means, said elements cooperating with the end fittings to bring the latter into tightly sealed contact during the utilization of the tensioning means, wherein the collar has at least one C-shaped spring connecting each of the articulated elements and giving the collar a semi-rigid structure, there being a clearance in a direction longitudinal with respect to the spring between the latter and each of the articulated elements in order to prevent the transmission of the tightening forces to the spring.
