Abstract: A method of terminating an optical fibre cable wherein an annular deformable member is compressed inwardly onto a cable threaded through it by causing an encircing cincture exhibiting `memory` properties to try to return to a remembered shape and size. The annular member includes a plurality of portions which are held apart by spacer material to define a passageway through which the cable is threaded, the spacer material being subsequently caused to deform e.g. by heating, so that under the force exerted by the cincture said portions are urged inwardly and grip the cable.
