An expansion dowel includes an axially extending cylindrically-shaped expansion sleeve (2) having an axially extending expansion region (5) with one of axially extending slots or grooves therein and a central bore (4) tapering inwardly toward a leading end of the sleeve facing in the setting direction (S). The central bore (4) is shaped to receive an expanding member (6). The expanding member (6) has a trailing end face in contact with a safety element (11) for preventing axial displacement of the expanding member (6) opposite to the setting direction. The safety element (11) has a radially outer circumferential surface that can be enlarged in the circumferential direction by a pin-shaped member (7) having a conically-shaped region which can be driven in the setting direction into the safety element. The expanding member (6) is shaped at its trailing end region for receiving a leading end region (9) of the pin-shaped member (7).
