Releasable connector and coupling assembly

A releasable connector 10 comprises a lower element 14 and an upper element 12; the lower element 12 having an engagement surface (20 figure lb), an undercut (24, figure le) and a latch 16 and the upper element 12 having an engagement surface (18 figure 1b),a tang 22, and a recess 30; wherein the releasable connector 10 is rotatably movable between a first configuration in which the engagement surfaces 18,20 abut and a second configuration in which the engagement surfaces 18,20 do not abut by the tang interfacing with the undercut; the lower 14 and upper 12 elements are releasably secured together by the latch 16 engaging with the recess 30 in the first configuration. The releasable coupling may be used with a coupler (70, fig 3) for coupling control means. The control means may be a Bowden cable (56, fig 3) or electrical wires
