Abstract
A hydraulic coupling device for connection to a multi-line hose including a plurality of hydraulic conduits bunched together 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. Each of the plug pins has a circumferential groove, and the thickness of the holder is greater than the width of the circumferential grooves in the plug pins. The plug pins are held in radial slots in the holder, the radial slots being so shaped as to retain the plug pins against axial movement with respect to the holder.
