A pipe coupling comprising a plurality of generally arcuate segments (1,2) adapted to abut one another end to end when fully made up; the segments (1,2) of the coupling being provided with two sets of axially separated keys extending radially inwardly thereof and adapted, in use, to engage in outer annular peripheral grooves (9,10) in the pipes (11,12) to be jointed by the coupling adjacent the ends thereof; an annular sealing gasket disposed between the keys for providing a seal for the pipes to be joined by the coupling; and means for coupling the segments together at their ends. The segment (1,2) ends have surfaces (5,6) for complementary mating one with another lying in a plane passing through the axis of the coupling and at right angles to the median plane of the coupling.
