Abstract

Device for connection between a flexible pipe 1 and a rigid tubular joining piece 2 intended to be fitted inside the flexible pipe. Two coaxial, rigid, tubular elements 3, 4 are disposed respectively inside and outside the end of the flexible pipe and embrace this end. The inner tubular element 3 and the outer tubular element 4 each present, in contact with the flexible pipe, two cylindrical portions of different diameters, 3a,4a-3b,4b, the one of larger diameter being located towards the free end of the flexible pipe. The portion of larger diameter 3b of the inner tubular element thus constitutes, on its inner face, a housing 5 for the O-ring, said housing being closed by an annular wall 8 fixed to the outer tubular element 4.
