Abstract
An expansion anchor includes an anchor bolt and an expansion sleeve which surrounds the anchor bolt. The expansion sleeve has an expansion tongue and an anchor tongue and the anchor bolt has a backward-pointing expansion slope for radially displacing the expansion tongue and a backward-pointing anchor slope for radially displacing the anchor tongue. The backward-pointing anchor slope extends more steeply than the backward-pointing expansion slope at least in some regions.
