Abstract of the Disclosure A detachable clip is disclosed separately fixturing each of two reinforcements extending along opposite sides of a heat exchanger core to one of two headers at opposite ends of the core during brazing of the core and the reinforcements to the headers at junctures thereof and wherein the reinforcements may be assembled prior to brazing with substantial air space at their junctures with the headers but not exceeding a prescribed limit. The clip is made of a material having a coefficient of thermal expansion substantially less than the reinforcements so as to draw the reinforcements and headers together during brazing through a distance at least equal to the prescribed air space limit to thereby assure contact at all the junctures between the reinforcements and headers during the brazing thereof.
