An osteosynthesis device, in particular for the spine, is described. The device comprises an outer spherical surface and a substantially cylindrical inner surface, designed to receive a rod of the device. The device is characterised in that the ring consists of two mating parts each being U-shaped and having a bottom and a pair of branches taking up a fraction of the axial dimension of the bottom. The distance between the branches is about the same as that of the rod diameter, their respective bottoms facing each other enclosing the rod, and their pairs of branches adjacent. The parts jointly define the outer and inner surfaces. The device is applicable to linkages adjustable at different angles.
