Abstract: In an exemplary embodiment, a U-shaped bracket forms pivot pins by means of the bent-out end areas of the bracket arms, which pivot pins are insertable (and held by the resilience of the bracket) in recesses of the car container sidewalls. The U-shaped bracket has its respective arms engaging in lateral slots of the container insert. The removable container insert may be lowered into engagement with the U-shaped bracket after assembly of the bracket with the car container, with the dimensioning such that the container insert prevents disengagement of the retaining pins. Outwardly inclined parts of the bracket arms may engage in close fitting elongated slots of the container insert so that the container insert pivots as a unit with the supporting bracket.
