An expansion dowel assembly is adapted to secure fastening plates in spaced relation onto a structure. The expansion dowel assembly includes an axially extending sleeve-like member including an expansion section arranged to be secured into the structure and a collar section. The collar section engages the facing plate between a bearing and an abutment. An axially extending part of the collar section between the bearing and the abutment is arranged to collapse in the axial direction so that the space between the bearing and the abutment corresponds to the wall thickness of the facing plate. The axially collapsible part permits the expansion dowel assembly to be used with facing plates of different thicknesses.
