Abstract
A hydraulic connection includes a connecting nipple, preferably of steel or of another metal, whereby, on the nipple's tube-shaped extension, a hydraulic hose is held by compression by means of a fitting. A swelling element is arranged between the extension and the hydraulic hose, the element being swellable in the hydraulic fluid. If hydraulic fluid were to advance through to the swelling element, the element will swell and block the path to more hydraulic fluid. Furthermore, by swelling, the element deforms the hydraulic hose in a radially outward direction. In this region, the hydraulic hose is held by a fitting in the form of a metal sleeve so that the hose may not be displaced. In this manner, the force of pressure on the hydraulic hose is increased in an annular zone.
