Hydraulic coupling device

A hydraulic coupling device for connection to a multi-line hose comprising a plurality of hydraulic conduits bunched together, a coupling device comprising:

• (a) a casing, a plurality of plug pins having at least one circumferential groove, and means for holding the plug pins within the casing,
• (b) each plug pin is connectable to a respective conduit of the multi-line hose,
• (c) the holding means including at least two retaining discs each having a respective aperture through which each one of the plug pins passes and having groove engaging portions to be tightly engaged with a groove of each plug pin,
• (d) each of said apertures having a larger diameter than that of the respective groove in the associated plug pin,
• (e) said retaining discs being displaceable with respect to each other to axially fix the plug pins with said groove engaging portions, and
• (f) means for maintaining the discs in their displaceable relationship with respect to each other within the casing.

A hydraulic coupling device for connection to a multi-line hose comprising a plurality of hydraulic conduits bunched together, the coupling device comprising:

• (a) a casing having a inner and outer surface,
• (b) a plurality of plug pins having at least one circumferential groove,
• (c) means for holding the plug pins within the casing,
• (d) each plug pin is connectable to a respective conduit of the multi-line hose,
• (e) the holding means including at least two retaining discs which are displaceable with respect to each other and have grooved engaging portions for tightly engaging within the groove of each plug pin,
• (f) said discs being effective to axially fix the plug pins when said discs are displaced with respect to each other, and
• (g) means located on the inner surface of the casing for maintaining the discs in their displaced relationship with respect to each other.
