Abstract
A heat exchanger, for example a condenser for a motor vehicle air conditioning system, comprises a matrix of cooling fins through which extend serpentine tubes consisting of hairpin shaped tubes joined by tubular junction pieces. The fin matrix is surmounted by an end plate. The heat exchanger is joined to an inlet or outlet flow pipe by a connecting device comprising a connecting block having a connecting element for connecting it to the flow pipe. The block has a recess in which the end of one or more of the heat exchanger tubes is sealingly mated, and is secured on the end plate of the heat exchanger by fastening means.
