A heat exchanger for a motor vehicle includes heat exchange bundle with a plurality of stacked tubes inside which a first heat-transfer fluid circulates, and an end flange arranged on each side of the stack of tubes which brazed to the heat exchange bundle. The end flanges include a flat body with a first surface that faces an aerodynamic element and a second surface, the brazing surface, opposite to the first surface and brazed to the heat exchange bundle. Attachment tabs receive the aerodynamic element and are arranged on the sides of the flat body, the attachment tabs projecting in the opposite direction to the heat exchange bundle. At least one extension of the flat body extends in the same general plane as the flat body and is arranged between a pair of attachment tabs on a same side of the flat body.
