A frame plate 11 for a heat plate has two ports 12, 13 to which two tubes provided with ring flanges 16, 17 are connected. The ports 12, 13 are situated so near each other that there is not enough room for the flanges 16, 17 of the two tubes to be juxtaposed with respect to each other. The problem is solved according to the invention in that at least one detachable spacer 14 is placed between the frame plate 11 and the ring-shaped tube flange 16 at at least one port 12, said spacer encompassing a connecting canal between the port 12 and the interior of the tube, and in that the tube flange 16 is further connected to the frame plate 11 by means of means 18 separate from the spacer 14 in such a way that the spacer is squeezed between the frame plate 11 and the tube flange 16. <IMAGE>
