The invention relates to a heat exchanger comprising a multiplicity of tubes (12) of oblong cross-section. The tubes (12) include end segments (14) engaged in corresponding holes (20) made in a manifold plate (22), with interposition of a sealing gasket (32), one portion (36) of which is compressed between the end segment (14) and a surface (30) of the corresponding hole (14), each end segment having a wall (42) reinforced by a peripheral lip (38) of the wall, which is situated at a distance from a free edge (40) of the said end segment. Application in particular to cooling radiators for motor vehicle engines. <IMAGE>
