摘要

The cover has a base (12), a circulating peripheral wall (14) arranged transverse to the base and a connecting tube, where the base and the peripheral wall are formed as one-piece from metal sheet and the connecting tube is arranged at the wall. A connecting passage is inserted in the peripheral wall, whose edge is deformed to a receiving area by adjusting height of the edge, where the edge is provided with a defined receiving contour. The peripheral wall is formed to have oval-shape in cross section. An independent claim is also included for a method for manufacturing a cover.
