An anchorage ( 7 ) for at least one pre-tensioned or stressed tensile element ( 1 ), wherein the tensile force is transmittable to an anchor body ( 2 ) by means of one or several wedges ( 3 ), comprises a wedge-shaped layer ( 32 ) which has a modulus of elasticity that is lower compared to the other parts of the anchorage ( 7 ), whereby the greatest thickness of the wedge-shaped layer ( 32 ), measured normal to the longitudinal axis ( 4 ) of the tensile element ( 1 ), lies in the region ( 5 ) of the anchorage ( 7 ) which is near the load. In order to distribute contact pressures evenly across the clamping length of the tensile element ( 1 ), the wedge ( 3 ) and/or the anchor body ( 2 ) is/are formed at least by two wedge-shaped adjacent layers ( 31, 32 ), with at least one of the layers ( 32 ) being formed from a material having a lower modulus of elasticity than the material from which the further layer(s) of the wedge ( 3 ) and/or of the anchor body ( 2 ) is/are formed, and the greatest thickness of said layer ( 32 ) is provided in the region near the load.
