A rear underride safeguard 1 intended for vehicles 2 comprises a girder 10, which is aligned transversely to the direction of movement of the vehicle 2 and fixed to the vehicle 2, and a displaceable girder 13, which is designed so that it can be moved in the longitudinal direction of the fixed girder 10. At one end of the displaceable girder 13 there is fixing tool 14 for the attachment of a working implement in the form of a side plough 3. The extent of the displaceable girder can be adjusted, if required, and a sliding movement can be achieved by means of a double-acting hydraulic cylinder, into which oil is fed from the hydraulic oil system of the vehicle 2. The hydraulic cylinder acts on the displaceable girder 13 by way of the shock absorber, the purpose of which is to protect the rear underride safeguard 1 and the working tools connected thereto from major mechanical stresses. Since the rear underride safeguard 1 has not been coupled to any working tool, the displaceable girder 13 is moved into a position in which the fixing tool 14 does not extend beyond the side face of the vehicle 2. <IMAGE>
