Abstract: A towing coupling to connect a towing vehicle to a trailer, the coupling comprising: a vehicle bar connected to the vehicle; a trailer bar connected to the trailer; an intermediate member adapted to be pivotally connected at a first end thereof to the vehicle bar; and, a releasable member adapted to be releasably and pivotally connected at a first end thereof to a second end of the intermediate member, and to be connected to the trailer bar at a second end thereof; wherein: a first pivot axis is defined by a first coupling arrangement connecting the first end of the intermediate member to the vehicle bar; a second pivot axis is defined by a second coupling arrangement between the intermediate member and the releasable member, the second pivot axis being in a substantially normal direction to the first pivot axis; and a third pivot axis is defined by a third coupling arrangement formed by first and second pivotally connected parts of either the intermediate member or the releasable member, the third pivot axis
