An expandable water hose assembly comprises a water hose and coupling means. The water hose comprises a flexible outer tube, a collapsible water impermeable flexible inelastic inner tube located inside the outer tube, and an elastic flexible member located inside the collapsible water impermeable flexible inelastic inner tube. The outer tube, collapsible inner tube, and elastic flexible member are movable from a retracted storage configuration to an extended deployed configuration upon application of water pressure within the water hose assembly. The elastic flexible member is in an untensioned state while in the retracted storage configuration and a tensioned state while in the extended deployed configuration. Upon removal of water pressure from within the water hose assembly, the elastic flexible member may return to its untensioned state and applies a retracting force to the hose assembly to urge the collapsible inner tube into a retracted storage configuration.

A terminal for making a hydraulic, electrical, or optical connection in an ink jet printing machine. The terminal extends along an axis XX, and its external surface includes: a cylindrical portion, including a contact end and having a first diameter (d1), this end being provided with hydraulic or electrical or optical connection structure. The external surface also includes a collar, having a diameter (d2) higher than the first diameter (d1), and a throat, the bottom of which has a cross-section, in a plane perpendicular to the axis XX, having at least one arc of circle portion having a third diameter (d3) lower than that of the collar, at least one planar part, and a part of this cross-section having a width lower than the third diameter. The throat continues with a connection device, for connecting to at least one hydraulic conduit or one electrical cable or one optical fiber.

Apparatus and method for inserting a hose coupling into a hose, the coupling and the hose having inner surfaces defining an inner diameter. A shaft has a first and a second end. A gripping member is associated with the shaft and is movable between a relaxed condition wherein the gripping member has a diameter less than the inner diameters of the hose the coupling and an expanded condition wherein the diameter of the gripping member is increased so that the gripping member grippingly contacts the inner surface of the hose to secure the shaft in the hose in a way that the second end of the shaft extends from the hose. A pusher member is associated with the shaft, and is engageable with the coupling and is movable along the shaft towards the gripping member to insert the coupling into the hose.
