The suction device has a suction unit with a suction opening (11,11a), which is connected with a suction channel (12,12a) that is integrated in the suction unit. Discharge openings (O1,O2) of the suction units have rectangular-shaped circumferential flanges with a flat stop surface. The flat stop surface lies at a common coupling point (KS) adjacent to another flat surface of a common, rectangular opening of a suction pipe (22). The flanges are covered with the discharge openings of the suction units, and are held with a pressure force on the latter flat stop surface by a holding unit (17). |
