A system provides self locking stakes for a load carrying vehicle which includes a load carrying surface on the vehicle with an opening therein for receiving a stake. Each elongated stake has an upper end for retaining a load on the vehicle and a lower end adapted to be received in the opening. A notch on a side of the lower end of the stake has a height at least equal to the thickness of the load carrying surface. A spring carried on either the surface or the stake provides a biasing force urging the stake toward the side provided with the notch, so that the notch engages an edge of the opening thereby securing the stake on the vehicle. Preferably the spring is in the form of an elongated wire spring attached to the stake so that the stake can be removed by manually pushing the stake against the bias of the spring and then extracting the stake.
