A device for connecting either one of two alternative incoming Bowden cables with an outgoing Bowden cable has a frame with a cam plate. Two mirror-image cam curves each has a valley surrounded by higher cam portions. The incoming cables are connected to opposite ends of a link arm, the ends of which are also provided with cam engaging rollers. The center of the link arm is via an intermediate link connected to a swing arm, the free end of which is connected to the outgoing cable. In neutral position, the link arm extends between the cam valleys. When one of the incoming cables is operated, the associated cam engaging roller will climb out of its valley, thereby pushing the link arm towards the opposite cam curve so that the opposite cam engaging means engages its cam valley to form a pivot axis for the link arm. The intermediate arm transfers the pivoting movement to the swing arm and outgoing cable.
