<p>A control box (1) includes a housing (2) in which is pivoted a control lever (7) having an aperture (29) in its lower arm (30). The bent end (28) of the core (27) of a flexible cable (25) is hooked into the aperture (29) operatively to connect the control lever (7) and the cable core. Swaged upon the cable casing (27) is a cable hub (31) having an annular groove (32) fitted into a part-circular slot in the rear wall (34) of the housing (2). The base (41) of the housing is open and its peripheral wall is slotted at (42) to provide guideways for a retainer slide (35) of a resilient material which is slid into those slots to cover the open base. The rear end of the retainer slide (35) includes a protuberance (40) which, when the slide is fitted to the housing (2), will ride over a shoulder (48) of the cable hub (31) and snap home in the annular groove (32) therein to engage the retainer slide with the cable hub. Such mutual engagement both positively retains the retainer slide (35) in the housing (2) and also anchors the cable casing (27) to the housing, preventing the cable casing from making translational movement. The front end of the retainer slide (35) has a longitudinal flange (38) which is positioned to one side of and adjacent the bent end (28) of the cable core (27), thereby acting as a stop to prevent the cable core from becoming detached from the control lever (7).</p> |
