Abstract
The present invention discloses a quick release hitch pin which comprises an elongated member having a handle thereon which includes a locking assembly. The elongated member has a rod disposed in a central bore spring tensioned outwardly having a plunger on its inner end positioned between a pair of balls positioned in apertures which balls are urged outwardly by the plunger. As the balls are urged outwardly they form a locking member against the underside of the tow bar thereby preventing removal of the elongated member or pin. Alternative embodiments disclose a pair of tabs communicating with the lower portion of a looped rod, with the tabs having tangs thereon which tangs contact the underside of the tow bar when in the extended position thereby preventing removal of the elongated member.
