A loading space cover for a rear loading space in a motor vehicle, includes at least one cover element for the at least partial covering of an upper side of the rear loading space. The cover element defines an upper limit of the loading space. To enable a hazard warning triangle to be carried in the motor vehicle with the least possible modification of components of the motor vehicle, the motor vehicle includes at least one fastening unit arranged on an underside of the cover element facing the loading space for the direct or indirect fastening of an accessory, preferably a hazard warning triangle, to the cover element.
