Abstract: A cargo retainer for separating cargo and preventing shifting of cargo within a vehicle during transportation is disclosed. The cargo retainer includes an elongate outer tubular member and two tubes telescopically received within the outer tubular member. The outer tubular member and telescoping tubes are preferably formed of polymeric material. Short metal reinforcement tubes are inserted in the outer ends of the telescoping tubes to strengthen the connection point between the cargo retainer and the support structure in the vehicle's cargo compartment. Latch members are attached at the outer ends of the telescoping tubes for attaching the cargo retainer across the width of a vehicle's cargo compartment. The latch members preferably pivot about an axis normal to the axis of the cargo retainer. A retraction mechanism is provided in the form of a tension spring connecting the inner ends of the telescoping tubes together. The telescoping tubes and latch members fully retract into the outer tubular member.
