Connection between two ends of tubes (1, 2) having swellings in the form of a sleeve tube, in each one of which ends is inserted a sealing member (8) which is located radially on the inner side against a reinforcing tube (5) fitted into the swelling. In order to avoid displacements of the sealing member, and in order to obtain, at the same time and by construction, easy handling, each of the swellings in the form of a sleeve comprises a length (4), the axial section of which is curved or in the form of a broken line, with both axial ends extending essentially as far as the radial level of the outer surface of the reinforcing tube (5). The sealing member (8) fills, as far as possible, the volume delimited by the internal surface of the length (4), on the one hand, and the external surface of the reinforcing tube (5) on the other hand. To each of the lengths (4) there may be connected cylindrical lengths (3) of greater diameter than that of the non-swelled part of the tube ends (1, 2) receiving the reinforcing tube (5). <IMAGE>
