An anchoring device (10) for anchoring tendons for structurally reinforcing a structure such as a concrete structure, where the anchoring device (10) has a longitudinal central axis (A) defining an axial direction (A), and in the axial direction a distal end (1) and a proximal end (2); and said anchoring device comprises an outer barrel (20) and an inner wedge (30); and said outer barrel (20) has a cylindrically or frusto-conically shaped inner surface (21) defining a cylindrically or frusto-conically shaped inner space (22); and said inner wedge (30) has a frusto-shaped outer surface (31) and a coaxial bore (32); and said frusto-conically shaped inner space (22) is configured for allowing said inner wedge (30) to be positioned at least partly in said frusto-conically shaped inner space (22) of the outer barrel (20) in the axial direction; said coaxial bore (32) of said inner wedge (30) is configured for receiving a tendon (15), wherein that said inner wedge comprises an inner and an outer portion (37,38), said inner portion (38) overlaps the outer portion (37) as seen in a radial direction, wherein said inner portion (38) overlaps said outer portion (37) as seen in a radial direction, wherein the inner portion (38) and the outer portion (37) are separated by a cut (36), the cut (36) is configured for increasing said overlap of the inner portion (38) and the outer portion (37) upon exertion of radially compressive forces on the wedge, thereby reducing the circumference of the coaxial bore (32) upon interaction with the outer barrel (20).
