A hydraulic connection comprises a connecting nipple, preferably of steel or of another metal, whereby, on said 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, said element being swellable in the hydraulic fluid. If hydraulic fluid were to advance through to the swelling element, said element will swell and block the path to more hydraulic fluid. Furthermore, by swelling, said element deforms the hydraulic hose in radially outward direction. In this region, the hydraulic hose is held by a fitting in the form of a metal sleeve so that said hose may not be displaced. In this manner, the force of pressure on the hydraulic hose is increased in an annular zone. A durable seal is achieved.
