摘要

overlapping pipe joint, pipe for use in conjunction with a second pipe and a pipe clamp to form an overlapping pipe joint, and method for telescopically coupling the ends of an inner and an outer pipe to each other. an overlapping pipe joint for use with vehicle exhaust systems that includes an end of the inner tube telescopically inserted into the outer tube end with the tube ends secured together by a strap-type clamp. the outer tube end includes a sealing zone having a collapsible sealing slit that allows the outer tube end to be pulled firmly onto the outer surface of the inner tube end by means of the strap-type clamp to thereby provide an airtight seal to fluid between the tubes. the sealing slit extends from one open end of the outer tube end and includes a pair of opposing side walls each having a tooth and a recess. As the strap-type clamp is tightened, the sealing gap collapses such that the sidewall teeth move to opposite recesses complementary, while the circumferential edges of the teeth snap together to form this. a fluid seal.
