INTERNAL HEAT EXCHANGE FOR CAR VEHICLE CLIMATE CIRCUIT, CLIMATE CIRCUIT AND CONNECTION PROCESS OF A CONNECTOR TO THE CHANGE. The present invention relates to a coaxial tubular type heat exchanger for motor vehicle climate circuit, said climate control circuit and a method of connecting a female connector to at least one end of the exchanger. The exchanger (E) defines an inner channel (11) for the low pressure fluid and, for the high pressure fluid, an outer channel (21) formed between a sleeve (10) surrounding the inner channel and a wrapper (20). which surrounds the outer channel, the sleeve extending axially beyond the end of the wrapper, at least one end (E1) of the exchanger being fitted with a connector (30) which is tightly connected over the wrapper and the sleeve and which it forms two fluid passage conduits (31 and 32) which communicate respectively with the inner channel and the outer channel. In accordance with the invention, the connector is connected to the wrap by a welding line, for example with arc (40) with the outside of the connector and to the sleeve by a sealing gasket (15) coaxial to the welding line and it seals tightly under an inner axial surface (34) of the connector, the gasket being separated from said line from a distance of at least 1 cm.
