The dowel comprises a body (1), with two elongate lateral arms (4), each having a groove and a bore, opening out between the arms (4) for a fixing screw (22) to pass through, a rocker (2) sliding and pivoting on the arms (4) of the body (1) by means of two pivots (10) in their grooves, with a ramp which interacts with the end of the screw (22) in order to cause the rocker (2) to pivot and an orifice for interacting, in the tilted position, with the fixing screw (22) and causing the rocker (2) to slide. Shearable pins (19) are provided for temporarily holding the rocker (2), detachable under the action of the screw (22) and which, when the dowel is inserted into a wall, drive the rocker (2) with the body (1). The body (1) and the rocker (2) are moulded simultaneously as a single piece from injectable material. The dowel can be used for fixing a component to a gypsum board.
