Abstract: The invention relates to an anchor sleeve (mesh sleeve 10) for injection fixing of an anchor rod, not illustrated, in a hole, not illustrated, drilled in masonry. The invention provides for the anchor sleeve (10) to be provided with inwardly extending supporting ribs (18) for the anchor rod and for the supporting ribs (18) to be arranged anchor sleeve chords instead of radially. The supporting ribs (18) hold an anchor rod coaxially in the anchor sleeve (10) and permit accommodation to different diameters as a consequence of deformation. By the arrangement of the supporting ribs (18) as chords, the supporting ribs (18) can be pressed more easily to one side and permit accommodation to a large range of diameters.
