Abstract
Tube passages slightly bigger than the tubes are formed in a plate. A soft resilient sheet is placed on one side of the plate. The tube is forcibly inserted in the tube passages and draws a portion of the sheet which is then cut. In the assembly the sheet, which has a bigger thickness than the interval between the tube and the tube passage, forms a flange beyond the tube plate.
