A flat seal with increased wear resistance with respect to relative movements and local excess pressure includes a base support plate provided with profiling on both sides in the region of the fastening of the seal, which profilings lead to the surface being enlarge in this region and hence the forces being reduced, and also cause an increase in the friction or even a toothing effect with the pressed-on flanges. The profilings can lie freely or can be additionally coated or filled with an elastomer material. Through the local separation of functions which is thus achieved between sealing effect and fastening effect, a flat seal is provided which shows less wear and is therefore able to function for longer, without additional elements or costly processing steps being necessary.
