Abstract: Disclosed is a hitch pin formed by a tubular body having a central, longitudinal slot adjacent its tapered, lower end. An elongated locking member is pivotally supported intermediate its ends within the slot and is movable between a retracted position in which the locking member is within the slot and a locking position in which the free end portions of the member extend sidewardly beyond the slot. A rod, pivotally attached to the locking member, extends through the central bore of the tubular body and at its upper end is formed into a camming loop which recedes into a slot in the upper end of the body when the locking member is in locking position. A loop handle, having a transverse member extending through the camming loop functions to move the rod and thus the locking member between its positions when the handle is moved from alignment with, to either side of, the pin body.
