Device for coupling helical tubes, characterized in that it is constituted by two internally smooth cylindrical tubular pieces, coupled concentrically to each other, the inner part having a central peripheral flange from which a skirt is derived that contours a part of the part provided with a propelled in helix, the remaining part being smooth, while the outer part is applied in the aforementioned smooth part of the inner part, making a stop in its flange, presenting an annular flange adjacent to the same flange, the rest being threaded to be applied in a box, cabinet or the like, the two parts being joined together with retaining means in the axial direction, with free rotation between them, so that the threaded part of the inner part is rotatably inserted in the helical tube to which it is applied, with insertion of the thread between the turns of the tube, until the same effected stop in the aforementioned walloon, while the lack of ends the diametrical limitation of the tube to cause its retention.
