ABSTRACT:
A pair of spaced parallel plates are affixed to and extend from a vehicle. The plates have bores formed therethrough in perpendicular alignment. A pin latch is affixed at one end thereof to the upper one of the plates in a manner whereby the pin latch extends parallel to and spaced from the one of the plates and is free from the one of the plates along its entire length except for the one end thereof. A pin device comprises a bar-like pin bar having first and second spaced opposite ends and a pin is affixed to the first end of the pin bar and removably extends from the one of the plates through the bores of both the plates in a manner whereby a ring coupled to another vehicle and positioned around the pin is secured on the pin by and between the plates. A spiral spring has first and second spaced opposite ends and is affixed at its first end to the second end of the pin bar. The spring is affixed at its second end to the one of the plates at a point spaced from the second end of the pin bar on the opposite side of the pin latch from the bores. The spring applies a force to the pin bar maintaining the pin bar between the pin latch and one of the plates about the pin as a pivot whereby the pin is removable from the bores upon the application of manual force against the force of the spring to move the second end of the pin bar so that the pin bar is moved about the pin as a pivot out of the pin latch thereby permitting the pin bar to be raised above the one of the plates to remove the pin from the bores.
