Patent abstract
An expansion anchor with a bolt as a first element and with an expansion sleeve, which at least partially surrounds the bolt, as a second element, is disclosed. The bolt has an expansion region for widening the expansion sleeve. One of the two elements has a groove running in the longitudinal direction of the expansion anchor and the other element has a projection, which engages at least sectionally in the groove. The groove has a narrowing, which inhibits an axial movement of the expansion sleeve relative to the bolt.
