There is at least one dowel sleeve ring bead arranged on an inner side of the dowel sleeve in an axial direction and tapering with respect to a symmetry axis in the direction of a plug-in opening. There is at least one expander ring bead formed on an outer wall of the expander. The expander ring bead has a pitch opposing the pitch of the dowel sleeve ring bead. There is at least one clamping element located in a free space between the dowel sleeve ring based and the expander ring bead. |
