The invention relates to an expansion anchor (1) comprising a bolt (10) as the first element and an expansion sleeve which at least partially surrounds the bolt as the second element, the bolt having an expansion region for expansion of the expansion sleeve, one of the two elements having a groove (72) that extends in the longitudinal direction of the expansion anchor and the other element having a projection that engages with the groove at least in sections. According to the invention, the groove has a restricted portion (73) which inhibits an axial movement of the expansion sleeve relative to the bolt. |
