Fixing device for concentric tubes, characterized by the fact that it consists of an external fixed tube in which another mobile or internal tube is attached, which supports the corresponding countertop and conical constitution in one of its generatrices. In which the head of a tightening screw screwed into the thread made in the thickness of the fixed tube is fitted, in a progressive stop, so that, in the downward direction, the aforementioned slit separates more from the outer tube wall, forcing to screw the screw more than in support and determined level produces a fixed stop effect that allows the ascent but not the descent, much less an unexpected collapse or accidental displacement due to lack of tightening.
