Anti-return device for fluid conduits that is essentially characterized in that it is constituted by a cylindrical tubular body that is hooked down to form an internally threaded neck and coupled superiorly to a valve body or inside which is located the shutter of the liquid vein that circulates by the general pipe to which the anti-return device is intended; having provided that said tubular body internally defines a vertical chamber in which a sphere is installed floatingly, having its seat in a chamfer that surrounds the orifice of the tubular body that communicates this with the valve body; with the particularity that the repeated cylindrical tubular body has radially with a fluid exit path whose inner diameter is smaller than the diameter of the sphere.
