Abstract

The invention relates to a metal expansion anchor sleeve (1) comprising an expansion zone (11) at a forward end. In said expansion zone (11), the anchor sleeve (1) is subdivided into cylindrical shell-shaped expansion tongues (5) by means of slots (4). Loops (3) are folded on the inside of the expansion tongues (5) such that the anchor sleeve (1) can be expanded by introducing a pin-shaped expanding element (13). According to the invention, the expansion sleeve (1) comprises incisions (22) that extend from longitudinal edges (21) of the loops (3). The length of said incisions (22) corresponds to a wall thickness of the anchor sleeve (1). Furthermore, the loops (3) are folded such that apexes of the folds are flush with a forward edge (23) of the anchor sleeve (1). The folds of the loops (3) do not protrude from the anchor sleeve (1) towards the front, thus preventing the loops (3) from being torn off at the folds thereof when the anchored anchor sleeve (1) is subjected to tensile stress.
