A trailer tongue hitch and ball clamp assembly includes a base portion loosely surrounding the hitch ball shank between its sphere and a tow bar transversely of the depending surface of the trailer hitch coupling socket forming member. A bridge portion of the clamp assembly, secured to the base portion, transversely overlies the upper surface of the hitch coupling for impinging it against the base member in surrounding relation with respect to the hitch ball sphere which permits the clamp assembly to move as a unit with the trailer tongue socket forming member in its horizontal and vertical pivoting movement relative to the hitch ball.
