Abstract:
A plug-in connection for joining pipelines to hose lines conducting a medium under pressure, comprising:an inner and an outer sleeve which hold a hose line to a pipeline;a pipe socket fitted over the outer sleeve;a protective element for locking the pipe socket to the outer sleeve; andmeans for sealing the inner and outer sleeves which is arranged between the inner sleeve and the outer sleeve and which abuts against an inner circumference of the pipe socket so that the medium under pressure flows inside of the inner sleeve and exerts pressure on the inner sleeve which presses the sealing means against the inner circumference of the pipe socket;wherein said inner sleeve further comprises a beveling surface and a flange surface so that the hose is pushed across the beveling surface and an outer edge of the hose is radially expanded by the flange surface, and said outer sleeve being shorter than the inner sleeve so that an opening is formed between the inner sleeve and the outer sleeve, and said sealing means further comprising a sealing lip formed from the radially expanded outer edge of the hose so that the sealing lip protrudes into the opening and lies tightly against the inner circumference of the pipe socket.
