The outer casing for a pipe coupling locates against a pipe end exterior and is provided with a gap-shaped aperture provided with devices or regulating the aperture comprising a rear piece (42) on each side of the gap-shaped aperture (34). On the outer casing side are a first rear piece (42) and a second rear piece (44) with through holes (45). The hole through the first rear piece has threads which work in conjunction with threads on a screw. - The hole through the second rear piece is so formed that a screw inserted through the second rear piece with its threads can work in conjunction with threads in the first rear piece when the gap-shaped aperture is widened to a maximum. |
