Abstract
Difficulties in obtaining consistent bonds of high quality between side pieces and tubular headers (10), (12) in heat exchangers are avoided in a side piece (42) that extends between the headers (10), (12) and which has circular recesses (48) at each end (44), (46). The recesses (48) define resilient fingers (56), (58) which may separate to receive the ends of the headers (10), (12) and frictionally grasp the same, eliminating the need for fixturing at this location and assuring a strong consistent gripping of the headers (10), (12), by the end piece (42) to assure consistent bonds of high quality.
