Abstract
An expansion dowel assembly includes an axially elongated dowel member with a flange at one end and arms extending from the flange to a junction member at the other end. By applying a force at the junction member and pulling it toward the flange, the arms can be buckled or displaced radially outwardly and collapsed in the axial direction. An abutment member is provided in the dowel for limiting the extent of axial collapsibility. The abutment member can be an axially extending sleeve member or an enlarged diameter part of a force applying member extending through the dowel member.
