ABSTRACT:
A band clamp used to connect tubular bodies such as vehicle exhaust system components. The band clamp has a band extending from a first end to a second end and includes a pair of spaced ribs extending at least part way between the first and second ends. A tightening mechanism is connected to the band and includes two clamp members movable toward and away from each other for tightening and loosening of the band. The band clamp further includes a gasket located on an inner surface of the band between the ribs and extending between the first and second ends. The use of the ribs with the interposed gasket provides a mechanical interlock of the band clamp with the tubular bodies while providing a hermetic seal at the junction between the two bodies.
