The cover (14) has a cylindrical interior body (12) telescope-like inserted into a coaxially arranged capsule-shaped external body (10), where the cover is attached at a front side of the interior body and/or at a front side of the external body. A radially aligned cover wall (16) and a guiding element (18) engage in the interior body and the external body, respectively. A fastening unit fastens the cover at a swirl body, and is provided at the cover wall. An attachment bar (20) is integrally formed at the cover wall. |
