Device for coupling pipes, of the type comprising an elongated body, axially drilled, which at one end comprises an independent nut, suitably retained with respect to displacements in the axial direction and capable of freely rotating, by means of which the hermetic coupling of the assembly to a corresponding threaded fitting, while at its opposite end said body is able to plug under pressure inside the pipe in question, and having a sleeve that wraps around it loosely and remains in place. Provision to be deformed on the pipe, pinching it and ensuring the tightness and mechanical strength of the coupling, characterized in that the fixing between the sleeve and the main body is carried out by providing in the latter a cylindrical intermediate zone, provided with grooves in the sense of the generators, which is available in pen pressurized into a corresponding extra-angled end zone, provided in the sleeve.
