Improved fluid transfer device, of the type comprising a central bellows body, each of whose emergent emergent necks has a flexible tubular duet coupled, acting respectively as a suction duet and as a liquid ejection conduit, which is essentially characterized by the fact that the suction duct incorporates a molded conical bushing, adaptable on any container neck, whose bushing has a bottom provided with an axial passage through which the suction duct slides, which through such mounting it can be placed in different emergency positions with respect to the bushing, depending on the depth of the container on which said bushing adapts, also counting each of the ends of the aspiration conduit and the expulsion conduit, with an internal valvular body, at time that the expulsion duct terminal has a flow regulator valve gives of liquid.
