Abstract
An expansion anchor includes a bolt as a first element and an expansion part as a second element. One of the two elements has a first rib running longitudinally along the bolt and the other of the two elements has a first groove running longitudinally along the bolt, where the first rib engages in the first groove. The one of the two elements has a second rib running longitudinally along the bolt and the other of the two elements has a second groove running longitudinally along the bolt, where the second rib engages in the second groove. A first catch of a snap connection is formed between the first rib and the first groove and a second catch of the snap connection is formed between the second rib and the second groove, where the first catch and the second catch hold the expansion part radially to the bolt.
