Abstract
A hitch pin for maintaining a clevis pin in a bore including a continuous wire member formed to include a straight portion ending in a constant radius hinge portion. A parallel portion extends from the hinge portion to a constant radius barb portion. The termination of the barb portion is located on the side of the straight portion opposite the parallel portion and resiliently maintained there by properties of the hinge portion as accentuated by material properties of the wire itself. The hitch pin may be installed in a bore defined in a clevis pin by applying force to the hinge portion after inserting the leadin portion in the bore. During installation, the barb portion is resiliently deformed about the clevis pin and returns to a preinstalled position when the hitch pin installation has been completed. Any forces attempting to remove the hitch pin cause the barb portion to strike the clevis pin presenting a mechanical obstruction to removal.
