An expansible fixing plug, having a sleeve portion, an expander body, and an expansion part which is arranged between the sleeve portion and the expander body, which expansion part has expansion elements which, in a non-expanded state, are integrally joined to the sleeve portion and to the expander body,
- wherein the expander body is movable towards the sleeve portion by means of an expander screw, with the result that the expander body expands the expansion part in such a way that, on expansion, the expansion elements become detached from the expander body at predetermined breaking points in such a way that, in an expanded state, they are separate from the expander body,
- wherein the expansion part has connecting elements which integrally join the sleeve portion and the expander body in the non-expanded state and also in the expanded state,
- wherein
- the connecting elements are interlockingly connected to the expander body.
