A Hitch Pin Clip is a securing device constructed from resilient yet bendable material, typically tempered steel wire, formed in an "R" configuration. It's alternatively referred to as an R-clip, hairpin cotter pin, or bridge pin. A hitch pin serves as a connector that temporarily secures two metal components together, frequently utilized within trailer receiver hitches. These fasteners feature a curved end or head that prevents slippage, while a clip mechanism secures the opposite end in position.
