  • the section 75 is followed by a section 78 of the receptacle 72 having anti-rotation contours 77 in which a rod section 79 of the tension element 58 is received in a manner secure against rotation.
  • the rod portion 79 as well as the portion 78 is polygonal, for example, approximately flat in cross-section rectangular, so that the rod portion 79 in the portion 78 of the recess or receptacle 72 can not rotate. Since the remaining portions of the tension member 58 are not twistable, the tension member 58 can not rotate in total in the receptacle 72.
  • the abutment head 60 is arranged at a free end of an adjoining the rod portion 79 end portion 80 which is received in a portion 81 of the receptacle 72.
  • the tension element 58 has a longitudinal play in the receptacle 72 with respect to the tension directions Z1, Z2.
  • the portion 78 which is a waisting of the receptacle 72, so to speak, with respect to the longitudinal axis L, in which the tensile directions Z1 and Z2 extend, shorter than the rod portion 79 so that it projects into the larger cross-sectional portions 75 and 81 ,
  • a scale 82 is preferably arranged, to which an index 83 of the drive assembly 11 points.
