The invention relates to a fixing element () for anchoring in a drilled hole, having a shank portion () and an expansion element (), there being arranged on the shank portion () an expander body () for expanding the expansion element (). The expansion element () has a plurality of arcuate expansion lobes (), each expansion lobe () being formed by two bridging portions () connected by a yoke (). The bridging portions () of the expansion lobes () together generate an envelope surface (M) of the expansion element (), which envelope surface (M) has rotational symmetry about the longitudinal axis (A) of the fixing element (). In order to provide a fixing element () which can be used both in a wide and also in a narrow drilled hole, the invention proposes that the yoke () have an arcuate curvature () which projects beyond the envelope surface (M) in the radial direction (R).
