<p>The device has a connecting piece fixed in a wall aperture of a base part i.e. main pipe. A support ring (8) is designed as a circular rim of radial support straps (12), which are arranged in a star shape. Axial holders (13a, 13b) project from the support straps in pairs. The straps are form-variably, connected by the holders. The holders of the adjacent straps facing each other are bridged by forming an inner boundary (14) of a slot (15). The slot is opened on a circumference side, and flanked by the holders and the straps. An independent claim is also included for a support ring.</p> |
