Abstract:
1. A clamp for coupling mating radially projecting flanges, each flange having a coupling surface and a tapered face remote from the coupling surface, the clamp comprising: at least a pair of component halves, each half comprising a generally U-shaped cross-sectional profile including a fastener for fastening the component halves together such that when the component halves are fastened, the recesses defined by the side limbs of the component halves face each other to define a central aperture therebetween, wherein the contact face of the side limb is inclined at an inclination angle in relation to a plane perpendicular to a central axis of the central aperture defined by the recesses of the components halves in a fastened position, and the non-contact face of the side limb is inclined at a shallower inclination angle than that of the contact face of the side limb in relation to the plane perpendicular to the central axis of the central aperture defined by the recesses of the components halves in the fastened position.
