Abstract
A hydraulic coupling device is provided for connection to a multi-line hose constituted by a plurality of hydraulic conduits bunched together. The coupling device comprises a casing, a plurality of plug pins housed within the casing, and a holder for holding the plug pins. The plug pins are each connectible to a respective conduit of the multi-line hose. The holder is constituted by at least two retaining discs, and each plug pin is provided with two circumferential grooves. The retaining discs are each provided with a respective aperture through which one of the plug pins passes. Portions of the retaining discs adjacent to the apertures can be tightly engaged within the grooves in the plug pins, by being radially displaced and/or rotated relative to one another. In this way, the plug pins are axially fixed relative to the retaining discs.
