摘要： An axially extending expansion anchor or dowel has an anchor body (2) with a first end region to be inserted first into a borehole (B) in a receiving material (G) and a trailing second end region in which a load can be applied. The first end region has an axially extending expansion region with at least two expanding tangs (7) separated from one another by axially extending slots. The first end region has a opening (11) into which an expanding body (12) is displaceable axially for radial expansion of the tangs (17). The axially extending opening (11) has an inner axially extending surface (10) closer to the axis of the anchor body and formed by a guide pin (9) of the anchor body (2) and an outer axially extending surface formed by the inner surface of the tangs (7). The expanding body (12) is basically sleeve-like shaped and has an inner surface which bears against the inner surface (10) of the opening (11). The outer surface of the expanding body (12) is, at least in part, wedge shaped. In the radially outwardly expanded state of the tangs (7), the expanding body (11) lies substantially flat against the inner and outer surfaces of the opening (11).
