P the invention relates to a method of attachment of a flexible conduit 5 on a rigid tube 1, according to which it equips the end 2 of the tube 1 by an overthickness 9, and it is engaged the end 6 of the conduit 5 on said end 2 of the tube 1 so as to place the extreme edge 8 of the duct 5 to the - addition of the flange 9 with respect to the end edge 4 of the tube 1. The extra thickness is carried out by fixing on the end 2 of the tube 1 a circle 9 which is initially separate from the tube 1 and which, after fixing, projects d9 with respect to the outer periphery 3 of the tube 1. / p & & p & an application is the production of assemblies which are not subject to unwanted dislocations. / p
