A fixing element, in particular a peg, for fixing bone fragments, ligaments or the like, has at least two outer sub-elements which divide the fixing element in the longitudinal direction with respect to a separating surface between the at least two outer sub-elements. The at least two outer sub-elements are of such a configuration and are so arranged relative to each other that the fixing element is adapted to be transferred from a compact condition into a laterally or radially expanded condition. The fixing element is of a dovetail-like configuration at its proximal end for coupling to an instrument for holding and introducing the fixing element. The fixing element has two notches which extend on opposite sides of the fixing element transversely with respect to the separating surface between the at least two sub-elements and which respectively extend over the sub-elements and which are so shaped that the depth of the respective notch decreases towards the proximal end of the fixing element and thus the width of the fixing element increases from a viewing direction along the two notches towards the proximal end of the fixing element. The width of the fixing element at the proximal end thereof being smaller than in a longitudinal portion adjoining the notches in the distal direction.
