The chamber insertion has a gas pipe (4) and a plastic cover body (12) is placed on the gas pipe. The plastic cover body extends to a mounting element (13), which has a radial extension with passages for clamping bolts (16). The gas pipe runs through the mounting element, and a gasket (10) which is made of elastic material attached to the inward pointing front edge of the mounting element is arranged on the plastic cover body. A plastic pipe (17) is attached to the free front edge of the gasket. Another gasket (18) made of elastic material is attached to the inner front edge of the plastic pipe. The gaskets are pressed firmly at the plastic cover body and at a plastic flange or a protective pipe (7). The plastic cover body consists of mineralized polyethylene.
