Abstract

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.
