Independent wedge for a vehicle wheel, intended to be placed on an uneven surface, such as a corrugated floor of a car-transporting railway truck, the said wedge being provided with a device making it possible to lock its rear part in a hollow or protuberance in the said surface, characterized in that it consists of one or more rods (1, 2) bent and joined together so as to comprise, apart from the rear locking part (8) : - a central part in the form of a porch with two offset transverse ribs (5, 4) intended to serve successively as supports for the wheel to be wedged ; - a central part (6) arranged, for example by bending or rolling, so as to give the above part elastic longitudinal flexibility ; - a front part (7) extending the above part (6) and consisting of two arms acting as a clamp intended to straddle the wheel to be wedged and resting on the surface by means of its lower part ; and - an axial part (9, 10), the front part (10) of which rests on the surface so as to be crushed by the wheel to be wedged, and the rear part (9) of which is raised so as to serve as a positive rear stop for the two offset ribs (5, 4) of the porch.
