Abstract
The expansion dowel includes an expansion sleeve (1) and an expanding member (5). The expansion sleeve 1 is provided with a bore (2) tapering in the setting direction as well as with open ended longitudinal slots (3). The expanding member (5) has a blind bore (6) open towards the setting side and has a lug (7) projecting from same at its opposite end, wherein the cross-sections of lug (7) and blind bore (6) are matched in such a way to one another, that a rated break point or failure point is formed. The force dependent response of this rated break point leads to a force dependent expansion while maintaining the driving or advance travel (X).
