A clamp suitable for joining a pair of tubular members, e.g., commercial truck exhaust pipes. One clamp (70) according to the invention includes an S-shaped band (72) having a pair of forward curved portions (76) on either side of a reverse curved portion (78). Attached to each forward curved portion (76) is a reinforcing bar (74) preferably forming a pair of D-shaped holes (75) suitable for receiving “half-carriage”bolts (100). The band (72) is preferably formed from Type 409 stainless steel to reduce costs. A fully preformed (cylindrical) embodiment (120) and flat embodiment (130) are also disclosed.

A clamp suitable for joining a pair of tubular members, comprising: (a) a ductile band having a length substantially equal to the circumference of the tubular members; (b) a pair of half-carriage bolts having a D-shaped portion disposed adjacent a head portion and a pair of hex nuts; (c) a first reinforcing member attached to one end of the band forming a pair of D-shaped holes suitable for receiving and engaging the D-shaped portions of the half-carriage bolts, said D-shaped holes disposed with the rounded corners thereof facing said band; and (d) a second reinforcing member attached to the other end of the band forming a pair of holes suitable for receiving the threaded portions of the half-carriage bolts, wherein when the clamp is placed about the joint between the tubular members and when the half-carriage bolts are inserted into the holes formed by the reinforcing members, the hex nuts can be threadedly engaged with the half-carriage bolts to draw the reinforcing members together and the band into sealing engagement with the tubular members, whereby the D-shaped holes prevent the half-carriage bolts from turning and decrease stress risers in the band adjacent the D-shaped holes.
