A brazed engine cooling radiator for a motor vehicle comprises a row of flat tubes arranged in a bundle alternately with cooling fins, with a structural member extending along one end of the bundle. A support member, for carrying an accessory, is in the form of a saddle which straddles the structural member. The back portion of the saddle has press formed tongues which co-operate with ribs of the structural member so as to guide the support member longitudinally. The side edges of the support member have teeth which are upset under the structural member so as to immobilise the latter. The teeth deform portions of the endmost cooling fin that lies between the base of the structural member and the adjacent tube. This support member is less costly to make and fit. It is fitted by seaming after the radiator has been brazed.

[ What is claimed is:] [1.] A heat exchanger comprising a bundle of parallel tubes arranged in at least one row and defining a longitudinal direction; at least one profiled structural member extending in the longitudinal direction and disposed at one end of the row; and at least one support member fixed on the structural member for receiving an accessory in a predetermined position with respect to the heat exchanger,wherein the support member comprises a sheet metal saddle having a back portion engaging on the structural member on a side opposite to the tube bundle, the saddle further including two side portions extending from the back portion substantially in the direction of alignment of the tubes on opposed sides of the bundle and structural member, the back portion being press-formed with portions projecting towards the structural member and co-operating with the profile of the structural member to guide the saddle with respect to the structural member in the longitudinal direction, each said side portion having an edge opposed to the back portion, the teeth of each said side portion being bent back towards the other side portion,wherein marginal regions of the structural member are trapped and hold the back portion of the saddle against the structural member while immobilising the support member in the longitudinal direction.
