An expansion sleeve for an expansion dowel has an axially extending expansion region with axially extending slots forming tabs between these slots. To enlarge the surface of the expansion sleeve for assuring the attainment of high anchoring values, the axially extending slots are formed free of any gaps. The gap-free slots can be formed by extrusion including radially pressing together the tabs between the slots.
