ABSTRACT:
The invention relates to a gripping edge (1) for a syringe with: a sleeve (7) with a first opening (9) for attachment to a barrel (2) of the syringe and a second opening (10). The gripping edge (1) comprises a flange (8) that is attached to the sleeve (7) at a distance from the first opening (9). A large number of catches (11), which project radially toward the inside from the inside wall (21) of the sleeve (7), are provided to engage in a groove attached to an outside surface of the barrel (2) or projections (13) and to fasten the sleeve (7) and, over this, the gripping edge (1) to the barrel (2), whereby a considerable number of openings, in particular a considerable number of lengthwise openings (14) and/or a considerable number of transverse openings (15), are cut out in the sleeve (7). As a result, a locking of the gripping edge (1) to the barrel (2) in the case of lower assembly forces is possible, by which a bursting tendency of the barrel (2), in particular during assembly, is considerably reduced.
