The groove extends coaxially to the opening and is open toward the heat exchanger tube and the end of the heat exchanger tube is pressed into the groove. The sleeve-like connection nozzles have a middle section (B), which is located in the plane of the tube sheet, and end sections, (A, C) which project on either side of the tube sheet.
