<p>The invention relates to a hydraulic coupling device, comprising a coupling unit, a holder block, and a lock nut (5). The coupling unit is mounted to the holder block by means of the lock nut (5), which is tightened in a thread at the nose end of the coupling unit. According to the invention, the lock nut (51) has a rotationally symmetrical outer contour (63, 51, 52, 53, 54). A plurality of grooves (55) distributed around the circumference are recessed in the outer contour. The grooves (55) extend axially inward from the end (56) of the lock nut (5) facing away from the holder block. The invention also relates to a lock nut (5) for a hydraulic coupling device, a mounting tool for the lock nut as well as a method for mounting a hydraulic coupling device.</p> |
