A method for connecting in a sealtight manner a flanged sleeve to a pipe, especially for subsea gas and oil ducts, comprises the steps of introducing the free end of the pipe into the flanged sleeve with a clearance, expanding the pipe within the sleeve with the aid of a resilient expansible body which is axially compressed, releasing the axial compression and withdrawing the expansible body. The radial expansion is such as to expand the pipe at its plastic deformation condition and the sleeve within its elastic deformation limit, so that a union is achieved between the tube and the sleeve which is virtually indissoluble.
