Abstract: An improvement in or relating to a hitch assembly for connecting a trailer to a towing vehicle. The hitch assembly consists of features which are moveable in a telescopic manner and/or in a rotational manner to allow the adjustable repositioning of a coupling member of a trailer for it to be conveniently connected to a tow ball of a towing vehicle. The hitch assembly consists of ratchet type features that when a movement of the trailer is provided by the towing vehicle, the hitch assembly will move towards a condition, substantially automatically, where the connection between the trailer and the vehicle becomes substantially rigid apart from the degrees of freedom of movement normally provided by the coupling. The ratchet type features can be made in operative to allow for a user to manipulate the position of the tow coupling of the trailer so as to achieve a coupling between the trailer and the tow vehicle without the trailer needing to be in an exact location in respect of the tow coupling of the trailer.
