ABSTRACT:
A casing (10) for receiving a heat exchanger (12) such as a heater or an air conditioner for a motor vehicle, has an opening surrounded by a rim (13). The heat exchanger is inserted into the casing via the opening. To fasten the heat exchanger therein, resilient lugs (18) having inwardly turned latches (21) project longitudinally from the rim. The lugs snap fasten onto a peripheral flange (16) around the water box (17) of the heat exchanger. Assembly is simplified and speeded by the arrangement, thereby reducing its cost.
