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.
L'invention concerne un système de raccord hydraulique comprenant une unité de raccord, un bloc de support, et un contre-écrou (5). L'unité de raccord est montée sur le bloc de support grâce au contre-écrou (5) qui est serré sur un filetage situé sur le bec de l'unité de raccord. Selon l'invention, le contre-écrou (51) possède un contour extérieur symétrique par rotation (63, 51, 52, 53, 54). Une pluralité de crans (55) distribués le long de la circonférence sont incrustés dans le contour extérieur. Les crans (55) s'étendent axialement vers l'intérieur à partir de l'extrémité (56) du contre-écrou (5) éloignée du bloc de support. L'invention concerne aussi un contre-écrou (5) pour un système de raccord hydraulique, un outil de montage du contre-écrou ainsi qu'une méthode de montage d'un système de raccord hydraulique.
