ABSTRACT:
A hydraulic coupling device is connected to a multi-line hose comprising a plurality of hydraulic lines housed within a flexible sheath. The coupling device comprises a cylindrical nut, a plurality of plug pins housed within the nut, and means for holding the plug pins within the nut. The plug pins are each connectible to a respective line of the hose. The holding means comprises a holding disc, a retaining disc, and a sleeve. The sleeve is connected to the sheath of the multi-line hose. Each of the plug pins is provided with a pair of longitudinally-spaced collars which define therebetween a peripheral groove. The retaining disc is provided with a respective aperture for each of the plug pins. Each of the apertures has a diameter which is slightly greater than the diameter of one of the collars of the associated plug pin. The holding disc is provided with a plurality of radial slots. The peripheral groove of each plug pin engages within a respective radial slot of the holding disc. The collars of each plug pin are positioned on opposite sides of the holding disc, thereby limiting relative longitudinal movement of that plug pin relative to the holding disc. Said one collar of each plug pin is positioned within the associated aperture of the retaining disc.
