The branch connection stub presents an outside surface of revolution and has at least one axial internal passage, a rear segment with a fastener flange, an intermediate segment, and a front segment having a free end presenting a circular outline suitable for being mounting by plane welding around a circular opening in the wall of the main pipe. The intermediate segment includes a first wall and a second wall forming between them an acute angle towards the internal passage. The branch connection stub is applicable to a hot heat exchanger for rocket engines.
