Simplified coupling device for pipes, characterized essentially by the fact that at least one of the mouths to be coupled with a tubular part has a threaded outer portion and a cylindrical end tubular extension with a smaller outer diameter than the outside of said tubular piece. Threaded and flush portion with an annular groove in which the end of a tube is plugged, the device comprising a nut that fits over the aforementioned threaded portion and has in its internal rear area an oblique semi-elastic annular flange that in the starting area presents a reduced section to facilitate bending, whose flange is slightly smaller in diameter than the diameter of said plugged tube, on which, when screwing the nut and leaning against the other piece, the expressed flange is applied with strong pressure, reaching to kneel in the tube, to the slightly deformable effect, with which the firm unión between the elements is obtained tubular coughs (Machine-translation by Google Translate, not legally binding)
