1. A gate catch assembly comprising:
a coupling sub-assembly adapted to mount to a gate member, said coupling sub-assembly including:
i) an outer sleeve slidably mounted to the gate member for axial movement relative to the gate member between a retracted position and an extended position,
ii) a locking element rotationally mounted to the outer sleeve for rotational movement relative to said sleeve between a locked position and an unlocked position, said locking element including a locking disc having a locking aperture configured to cooperate with a locking bolt associated with the gate member, the locking aperture adapted to:
a) permit passage of the locking bolt during axial movement of the outer sleeve toward the retracted position with the locking element rotated into the unlocked position;
b) misalign with the locking bolt to prevent its passage on axial movement of the outer sleeve from the extended position with the locking element rotated into the locked position;
a catch sub-assembly configured to be releasably engaged by the coupling sub-assembly, said catch sub-assembly including an engagement arrangement designed to be engaged by the outer sleeve of the coupling sub-assembly in its extended position,
wherein the outer sleeve includes a circumferential keyway configured to be engaged by a corresponding key radially extending from the locking disc of the locking element.
