An annular clamping flange for use in clamping a first pipe end portion to a second pipe end portion in an engine exhaust system includes a first arcuate flange portion and a second arcuate flange portion co-operable therewith to form a pipe receiving aperture. Each flange portion has at least one clamping bolt receiving aperture having a longitudinal axis parallel to the longitudinal axis of the pipe receiving aperture. Each flange portion also has opposite ends each having a connecting bolt receiving tubular lug on the laterally outer side thereof, the tubular lug having a longitudinal axis substantially tangential to the pipe receiving aperture. The two flange portions can be positioned around a first pipe end portion and connected together by connecting bolts passing through respective pairs of adjacent tubular lugs on the first and second flange portions, and the annular flange can then be secured to a second pipe end portion by clamping bolts passing through the clamping bolt receiving apertures.
