Abstract
A heat exchanger, especially a motor vehicle radiator, comprises a bundle of finned tubes open into a header consisting of a header casing and a header plate. The ends of the tubes in the bundle are sealingly fitted in holes in the header plate, and at least one immobilizing element passes through the header plate and extends beyond the latter on the same side as the tubes, and in a direction parallel to the longitudinal direction of the tubes. The immobilizing element is abutted on a part of the tube bundle, in such a way as to oppose any relative displacement, in particular by pivoting or torsion of the tube bundle with respect to the header plate.
