The invention relates to a fastening device (1) for fastening a coupling piece (3) of a hose coupling to a hose end (2). The hose end (2) is placed over or pulled onto an insertion area (8) of the coupling piece (3) and is radially pressed inward by the fastening device (1) when in the fastened state. The fastening device (1) comprises a retaining element (5) and a clamping ring (6). The clamping ring (6) is externally placed around the retaining element (5) in a manner that permits it to be displaced around said retaining element (5), which is thereby radially pressed inward into the outside (13) of the hose end (2) by an axial displacement of the clamping ring (6). In addition, the retaining element (5) consists of two or more separate partial elements (4) each of which extending over a partial area of the circumference of the retaining element (5) and being radially pressed inward into the outside (13) of the hose end (2) by the clamping ring (6). Each partial element (4) has an inwardly directed projection (11), which protrudes into a recess (16) provided inside the coupling piece (3). |
