Abstract: An annular clamping nut which is provided for being placed onto the end of a tie bar, in order to brace the latter, and which has in addition to a central recess for receiving the tie bar parallel to a longitudinal direction passages at uniform radial spacings in the ring circumferential direction which are directed parallel to the longitudinal direction of the central recess and are provided for receiving clamping screws. An external thread is provided on the outer surface of the clamping nut, which outer surface is arranged on a side which lies substantially opposite the wall of the central recess, which external thread runs substantially in the ring circumferential direction of the outer surface.
