A flange fitting 20 for a pipe 14 comprises a flange ring 26 that is located around the pipe 14 and has a plurality of angularly spaced fixing holes 30. It further comprises a retaining ring 22 located around the pipe 14 within a groove 16 in the outer surface of the pipe, which in use restricts axial movement of the flange ring 26 on the pipe 14. The retaining ring 22 has a plurality of angularly spaced reduced-profile sectors 34 in regions corresponding to the positions of the fixing holes 30. These sectors can have a cross sectional area per unit angle less than that of the ring as a whole, and the outer profile of the sectors is substantially linear. |
