A flexible remote control mechanism comprising a flexible force-transmitting inner member (1) which is axially displaceable relative to an outer guiding conduit (3) comprises an adjustment means (5) which engages a thread (3a) on the conduit so as to be displaceable therealong by screw action but wherein the elements (9) which co-operate with the thread are retained in operative position by a spring (10). When the adjustment means (5) is subjected to axial forces above a certain value the elements (9) becomes forced out of engagement with the thread to allow displacement of the adjustment means along the conduit. The adjustment means can therefore operate in either of two modes: a rotational mode for fine adjustment and a non-rotational mode for self-setting adjustment under excess load. <IMAGE> |
