ABSTRACT:
An improved hitch pin assembly for releasably connecting a towed vehicle to a towing vehicle is disclosed. The hitch pin assembly includes a shaft and a generally C-shaped retaining arm, one end of which is pivotally supported at the top of the shaft for rotation between a first position in which it locks the pin in place in service and a second position in which it does not interfere with the removal of the pin. A magnet is positioned on the pin to retain the arm in the first position under most service conditions. The other end of the C-shaped arm includes a foot portion or guide bars to restrict that end from lateral movement relative to the shaft.
