Abstract: A trailer decoupling prevention device for preventing the trailer from decoupling from a trailer hitch mounted on a towing vehicle. The trailer decoupling prevention device comprises a bracket, and a connector assembly to connect the bracket to the trailer. A lower plate is movably supported by the bracket. A lower plate stop assembly is provided for selectively permitting movement of the lower plate between a coupled position and an uncoupled position. In the coupled position, at least a portion of the lower plate is positioned to prevent the trailer from being removed from the trailer hitch. In the uncoupled position, the lower plate is positioned to permit removal of the trailer from the trailer hitch. A unique coupling member for selectively coupling a flexible linkage to an attachment member is also disclosed.

Abstract: A safety connector for securing a trailer to a towing vehicle having a trailer hitch mounting member. The safety connector includes a trailer hitch adapted to be secured to the trailer hitch mounting member of the towing vehicle. The trailer hitch has a lower portion adapted to extend a distance below the trailer hitch mounting member when the trailer hitch is secured to the trailer hitch mounting member. A spool is connected to the lower portion of the trailer hitch such that the spool is positionable below the trailer hitch mounting member. The spool has a first shoulder portion spaced a distance away from the trailer hitch mounting member, and a medial portion positioned in between the first shoulder portion and trailer hitch mounting member. The medial portion has a diameter less than the diameter of the first shoulder portion. A base plate is connectable to the trailer. The base plate has a thickness less than a length of the medial portion, and a slot formed therethrough.
