A pipe coupling with an anchoring arrangement for locking the pipes together axially is described. The anchoring arrangement comprises a tubular casing (10), a frusto-conical gripping ring (40) with inwardly projecting gripping teeth 42 and tensioning bolts (17) for tightening the casing (10) about the frusto-conical gripping ring (40). The frusto-conical gripping ring (40) is formed of a plurality of arcuate segments (40a) and (40b) which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.
La présente invention concerne un raccord de tuyaux comportant un moyen de blocage permettant de bloquer axialement ensemble les tuyaux. Le moyen de blocage comprend un corps tubulaire (10), une bague de retenue tronconique (40) pourvue de dents de retenue (42) saillantes vers l'intérieur et des boulons de serrage (17) servant à serrer le corps (10) autour de la bague de retenue tronconique (40). La bague de retenue tronconique (40) est formée d'une pluralité de segments arqués (40a) et (40b) qui se chevauchent pour former une bague complète. Le fait que la bague de retenue soit formée de segments permet à ladite bague de retenue de s'adapter à des tuyaux dont la section n'est pas véritablement circulaire et d'assurer une meilleure retenue sur le tuyau qu'une bague de retenue formée monobloc.
