A disposable injection device (1) has an injection cylinder (2) that contains a piston (8) and a piston rod (6) linked to the piston in particular by a coupling device (7). The piston rod is preferably longer than the injection cylinder (2). On the side of the ampule that faces away from the piston rod (6) is arranged a coupling arrangement (3) for coupling an injection needle (4) to the injection cylinder (2). A trigger (9) and/or a warrant seal (27) are coupled to the piston (8) and/or to the piston rod (6). |
