A band clamp that connects overlapping pipe ends includes a band, a tightening mechanism, and a gasket. The band has a radially protruding rib, a first lateral section that extends from a side of the rib, and a second lateral section that extends from another side of the rib. The tightening mechanism connects to the band and is operable to tighten the band, and the gasket is received in the rib. In one example, an axial width of the lateral sections are within a range relative to an axial width of the rib, and in another example, the lateral sections are angled inwardly with relative to an axis of the band.
