Improved anti-return valve for fluid pipes, characterized in that the fitting in which it is housed determines an internal annular partition and has a sealing body consisting of a piece in the shape of a top having an accurate double conical configuration of juxtaposed bases, with conicity in both sides, such a piece forming a tail according to a threaded rod at its end where a circular plate with openings is threaded, between which and the wall of the septum of the fitting is interspersed a helical spring that keeps the assembly located axially, in a position in which the head of the obturator body is seated against the surface of the transverse septum of the fitting, preventing the passage of the fluid.
