The invention relates to an expansible fixing plug having limbs extending in a longitudinal direction of the fixing plug, from which limbs expansion elements project in opposite circumferential directions. The invention proposes constructing the expansion elements in the shape of hooks and so as to extend between one another with a spacing so that they connect the limbs by means of interlocking connections which come into effect after flexion or torsion of the expansible fixing plug or after buckling out of the limbs. The buckling, flexural and torsional strength of the fixing plug is increased. |
