A fastening element for fitting into a drilled hole, which has:
- an expandable sleeve (1) and
- an axially movable anchor (2), the sleeve inside surface and the anchor outside surface being designed such that the anchor (2), upon its axial relative movement with respect to the sleeve (1) in the direction out of the drilled hole, exerts radial forces on the expandable sleeve (1) in such a way that the sleeve (1) is fixed in the drilled hole;
- a flexible drawing means (6), which is receivable in a bearing element (5) with locking means for fixing the drawing means (6) which has on one or more sides means for preventing an axial return movement of the anchor in the direction into the drilled hole.
