a tie rod to be arranged in a connecting recess of the workpiece;
a buttress body to be arranged in a buttress recess of the workpiece communicating with the connecting recess, wherein the buttress body comprises an insertion receptacle for the insertion of an insertion section of the tie rod along an insertion axis and a support surface arrangement for support on the buttress recess of the workpiece, wherein at least one support surface of the support surface arrangement extends, transversely to a longitudinal axis of the tie rod inserted into the insertion receptacle, so that the tie rod is supported with respect to its longitudinal axis on the buttress recess;
a clamping body for clamping the insertion section of the tie rod in the insertion receptacle; and
at least one support body having a flat shape having opposing flat sides and narrow sides, extending between the flat sides for formfitting support at least in sections in the connecting recess or the buttress recess of the workpiece,
wherein the insertion receptacle, transversely to the insertion axis, has an alignment transverse width, which is suitable for aligning the tie rod with respect to the buttress body, and which is greater than a movement play necessary for the insertion of the tie rod into the insertion receptacle, and
wherein the at least one support body comprises a buttress body receptacle for the buttress body, in which the buttress body engages in the assembled state of the anchoring fitting.
