simplicity identical or very similar parts in comparison with the clamping connector 16 are given the same reference numerals modified parts or elements of the clamping connector are explicitly described and given their own reference numerals a second embodiment of a clamping connector provided altogether with the reference numeral 120 is illustrated in fig6 and 7 a tensioning member provided altogether with the reference numeral 122 differs from the tensioning member 50 due to the fact that instead of the two thread sections 64 and 68 adjacent to the bearing section 62 and the cylindrical section 66 respectively a respective cylindrical section 124 and 126 respectively is provided arranged eccentrically in relation to the longitudinal axis 60 in addition in comparison with the clamping connector 16 a hollow cylindrical section 128 is provided instead of the conical actuating surface section 44 and an outer surface of the cylindrical section 124 slides on this hollow cylindrical section as a result of rotation of the tensioning member 122 and can move the offset bridge 130 provided altogether with the reference numeral 130 in the direction towards the bar 14 the clamping member 86 with its actuating surface 88 a can be displaced in an analogous way by means of the cylindrical section 126 in the direction towards the clamping section 84 whereby the bar 14 can be held in a clamping manner in the bar receiving means 82 therefore interacting actuating and slide on surfaces are also provided in the case of the clamping connector 120 wherein these are not inclined relative to the longitudinal axis 60 slide on movement is brought about on account of the eccentricity of the cylindrical sections 124 and 126 wherein this eccentricity is apparent.
