ABSTRACT:
A control box includes a housing in which is pivoted a control lever having an aperture in its lower arm. The bent end of the core of a flexible cable is hooked into the aperture operatively to connect the control lever and the cable core. Swaged upon the cable casing is a cable hud having an annular groove fitted into a part-circular slot in the rear wall of the housing. The base of the housing is open and its peripheral wall is slotted at to provide guideways for a retainer slide of a resilient material which is slid into those slots to cover the open base. The rear end of the retainer slide includes a protuberance which, when the slide is fitted to the housing, will ride over a shoulder of the cable hub and snap home in the annular groove therein to engage the retainer slide with the cable hub. Such mutual engagement both positively retains the retainer slide in the housing and also anchors the cable casing to the housing, preventing the cable casing from making translational movement. The front end of the retainer slide has a longitudinal flange which is positioned to one side of and adjacent the bent end of the cable core, thereby acting as a stop to prevent the cable core from becoming detached from the control lever.
