A heat exchanger has a header plate which comprises a substantially flat base wall, which defines over at least part of its periphery a recess for receiving a claw element of a header cover. This recess is bounded on one side by projections formed on an inner face of the base wall, and on another side by a bent-back edge portion, from which retaining lugs extend. These retaining lugs are bent back to secure the header cover in position. The invention is applicable to heat exchangers for motor vehicles.
