Device for coupling helical tubes, specifically those defined herein, characterized in that it is constituted by a cylindrical tubular body, in rigid material, which has in its center an annular projection for its manipulation, an external threaded end for application in a box, cabinet or similar, and another end with external thread and diameter of the same internal characteristics that the flexible tube object of coupling, and by a nut of equal helical pitch and diameter that the outside of the tube, so that the said nut is mounted in the tube, at a certain distance from the free end of it and in it the tubular body is introduced by its corresponding part, until the tube is topped in the central projection, the nut being then moved towards said end until reaching said projection and press against it, with which the tube is retained under pressure between the threads of the nut and the body tubular.
