Abstract
An expansion dowel assembly consists of an axially extending sleeve and a spreading element. Tongues are pivotally displaceably connected to the sleeve and are located one after the other along the axial direction of the sleeve. The tongues are split in the axial directions and can be pivoted inwardly and outwardly relative to the sleeve. Lugs are formed on the radially inner surface of the tongues and project axially beyond one end of the tongues. The lugs afford axial support for the tongues pivoted outwardly relative to the outside surface of the sleeve. The spreading element holds the tongues in the outwardly pivoted condition so that the tongues provide a mechanical lock for the sleeve within a hollow space within a structural member.
