A motion transmitting remote control assembly (10, 10') including a conduit (12), and a motion transmitting core element (14) movably supported by the conduit (12). An adjustment device (18, 18'), comprising first (20, 20') and second (22) members, is provided for adjusting the effective length of the core element (14). The first member (20, 20') and the second member (22, 22') include coacting ratcheting teeth (36, 38) to limit relative motion between the first (20, 20') and second (22, 22') members to one direction. The first (20, 20') and second (22, 22') members have elliptical cross sections with the first member (20, 20') being molded of a rigid organic polymeric material. The second member (22, 22') is molded of a resilient organic polymeric material for deforming inwardly along its major diameter in response to a pinching force applied thereto, and outwardly along its minor diameter to disengage the ratcheting teeth (36, 38) allowing relative longitudinal movement in both directions. Upon removal of the force, the second member (22, 22') returns to locking engagement with the first member (20, 20').
