A tunnel section of a connector for a fiber-optic cable has a washer with keys that extend radially outward. The washer fits loosely over the outer surface of the tunnel, but it is locked in a fixed radial position, for example, by matching flat surfaces along chords of the tunnel and the center hole of the washer. When one of these keys is bent downward, it projects into the space that would normally be occupied by a sleeve on the cable connector. The sleeve has a key way that receives the key when the connector is in the matching radial position. When maintenance personnel have rotated the cable to the radial position for best optical characteristics, the nearest key is bent into its locking position and the connector is assembled with the key extending into the key way of the cable connector.
