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 retaining disc for holding the plug pins. The plug pins are each connectible to a respective conduit of the multi-line hose. Each of the plug pins has a circumferential groove, and the plug pins are held against axial movement in radial slots in the retaining disc. Each of the radial slots has a first portion whose width is greater than the maximum external diameter of the associated plug pin, and a second portion whose width is less than that of the maximum external diameter of the associated plug pin, but which is greater than the diameter of the circumferential groove in that plug pin.
