ABSTRACT:
A hose coupling having a fixation collar with a tapered inner surface to be joined with a clamp for the coupling in which several jaws in the shape of tapered sectors are engaged in the collar while leaving a clearance between two successive jaws which form a substantially cylindrical surface surrounding the outer surface of the hose to be connected. A cylindrical sleeve is engageable inside the hose and is formed with a flange for bearing against the end face of the jaws and a tip portion which is slidable in a coaxial bore of the clamp, the diameter of said bore being greater to the inner diameter of the hose, so that a differential pressure area is established which applies pressure to the tip of the sleeve to drive it in a direction such that the flange engages the jaws.
