The unit (1) has a section (5) arranged in a swivelable manner around a rotation axis (X) against another section (4). A pre-tensioning device (8) pre-tensions the section (5) against the section (4) in a predetermined tensioning direction, where the pre-tensioning device is arranged sectionally around the swivelable axis. An area (9) of the section (4) is pressed to a rod-shaped object e.g. Christian tree. The sections (4, 5) include a housing (10) running around the swivelable axis, where the housing completely surrounds the pre-tensioning device in a circumferential direction. |
