ABSTRACT:
A connecting tube for a fluid header of a heat exchanger, especially a tubular header for a condenser of an air conditioning installation for a motor vehicle, comprises a cylindrical tubular body delimited by a metallic wall and extended by a flattened tubular end portion formed by deformation of the wall and arranged to be fitted into an oblong aperture formed in a metallic wall of the fluid header. The connecting tube has at least one shear cut, formed in the thickness of the wall and extending over part of the periphery of the connecting tube in a region lying between the body and the flattened end portion. The shear cut defines a frontal lip which bears against the wall of the fluid header after the flattened end portion has been fitted in the latter.
