Abstract
An expansion dowel consists of an axially extending sleeve slotted for a part of its length and an axially extending expansion body insertable into and displaceable through the bore in the sleeve for radially expanding the sleeve. The expansion body has at least one axially extending recess in its outer surface so that the expansion body can deform along the recess after a certain expanding force has been achieved. Further, an axially extending bore can be formed through the expansion body with the recess opening into the bore.
