Abstract: A collection of different sets of apparatus for holding vehicle accessories and joining them to differently configured vehicle cargo sockets. Due to the diversity of extant cargo socket constructions, even within a single vehicle, no single set of apparatus suffices to join an accessory to a socket. Therefore, to serve the singular purpose of joining an accessory to a vehicle cargo socket, multiple different connections are required. The difficulty of providing accessory connections is further exacerbated by the fact that socket constructions change from manufacturer to manufacturer; from model to model; and from year to year. Therefore, a collection of different sets of connections is required. Otherwise, an ongoing multitude of patents would be required to satisfy a single purpose. Thus, the present invention is a collection of different sets of apparatus, all having a singular purpose of joining accessories to vehicles.
