ABSTRACT:
A clamp particularly suited for crimp joining the telescoped end portions of thin walled tubing which is prone to inward collapse when overly constricted. The clamp includes an upper and a lower member each of thin metal material and each forming a curved mid-portion the arcuate edge of which contacts the surface of the outer telescoped tube member. Overlying portions at one side of the two clamping members forms a hinging action about the tube. At the opposite side of the members, tubular contours are formed in aligned relationship to one another to receive a bolt and nut fastener. The fastener is operated to draw the upper and lower members together about the exhaust tubes. Prior to operation of the fastener, the configuration of the members is such that a gap is formed between the facing end surfaces of the adjacent tubular portions. As the nut-bolt fastener draws the upper and lower members together and crimps the tubes together, these end surfaces move toward one another until engagement thus establishing a desired limited clamping and crimping action on the tubes.
