A band clamp as defined in claim 7, wherein said clamp members are each located at one of said first and second ends and comprise unitary portions of said band, said band including a pocket located at each of said first and second ends, and wherein said band clamp further comprises a tongue secured to said band within the pocket located at said first end, said tongue extending beyond said first end and into the pocket located at said second end, wherein said tongue provides a seating surface for said gasket at said first and second ends, with said seating surface being substantially continuous with said central portion of said band.20. A band clamp as defined in claim 19, wherein each rib extends circumferentially along said band from one of said pockets to the other of said pockets.21. A band clamp as defined in claim 20, wherein said pockets each have a depth that is greater than the depth of said clamping ribs.22. A band clamp as defined in claim 19, wherein said gasket comprises a strip of compressible material that extends from an edge of one of said pockets to an edge of said tongue that is located adjacent said edge of said one pocket.23. A band clamp as defined in claim 19, wherein said gasket extends beyond said tongue such that opposite ends of said strip overlap when said band is tightened.24. A clamping assembly for connecting first and second tubular bodies, comprising:a first adapter having a first edge flange at one axial end and a second edge flange at a second axial end, said first edge flange being adapted to be secured to an outer surface of the first tubular body and said second edge flange being adapted to be positioned over an outer surface of the second tubular body, said first adapter including a first circumferential rib located at said second edge flange; a second adapter having a second circumferential rib and being capable of being secured to an outer surface of the second tubular body such that said second circumferential rib is adjacent said first circumferential rib of said first adapter with said ribs overlying the second tubular body; and a band clamp comprising: a band extending from a first end to a second end and including a pair of spaced clamping ribs extending at least part way between said first mid second ends, said clamping ribs being spaced from each other by a distance that permits mating of each clamping rib with a corresponding rib from one of the two adapters when the band is assembled over adjacent axial ends of the two adapters, and a tightening mechanism connected with said band and including two clamp members movable toward and away from each other to draw said first and second ends toward and away from each other for tightening and loosening of said band. 25.
