The device is fastened in a fixture (2) by means of the first (4) of the two screws (4, 5). The second screw (5) is tightened so that it locates against the first, preventing it from becoming loose. A part of the device is produced using a tube which is cut on the slant. The first screw (4) is fitted in one of the two parts thus obtained, and then the two parts are turned through 180 deg. in relation to each other, and welded together again, thus producing the angled component (3). |
