An improved clamp assembly for clamping the overlapping ends of metal tubes in an exhaust system. The clamp assembly includes a metal ring having a pair of overlapping end portions disposed in side-by-side contact. A generally U-shaped bracket is secured to each of the end portions and each bracket has a pair of opposed legs connected by a web portion. Extensions project longitudinally outward from the end of each leg and the extensions are offset laterally from each other. One leg of each bracket is welded to one of the end portions of the ring and the welded leg is bent adjacent the weld to position the first extension in slidable contact with the other end portion of the ring. The extension of the opposite leg is disposed in side-by-side relation with the first extension and also serves to slidably receive the opposite end portion of the ring. A bolt extends through aligned openings in the brackets and the head of the bolt bears against the side edge of one bracket while a nut threaded on the opposite end of the bolt bears against the side edge of the other bracket. By threading down the bolt, the ring is contracted in diameter to provide a low cost, 360 DEG C. closure for clamping the tubes.
