AbstractA coupling unit comprising a first coupling part and a second coupling part. The second coupling part can be displaced longitudinally relative to the first coupling part by means of screw threads or the like. The first coupling part is equipped with a first nut-shaped section and the second coupling part with a second nut-shaped section. The second nut-shaped section has a cross-section measurement which allows passage of the internal surface of a tightening and/or loosening sleeve, when the latter is passed over the second nut-shaped section, to co-act with the first nut-shaped section.
