A ball coupling device comprising a socket assembly, configured to assume an operative condition in which it defines a socket to capture a tow ball such that there is formed a sliding 5 fit, permitting relative rotation, between the tow ball and socket or assembly, and to assume an inoperative condition whereby the tow ball and assembly can be decoupled, the assembly being configured to define in the operative condition an opening, disposed about a neck via which the tow ball is supported, having a width, parallel to a rotational axis extending centrally through the tow ball and perpendicular to a central axis of the tow ball that extends 10 top-to-bottom therethrough, sufficient that the neck passes through the opening, and a length sufficient to permit relative displacement between the neck and assembly and thus relative rotation between the tow ball and the assembly or device about said rotational axis.
