Abstract: The invention relates to a method for deforming through high inner pressure at least two hollow bodies (2, 3) having each at least one opening, especially metal tubes or metal hollow profiles. A theoretical rupture point (11) is first defined in the external wall (2a) of said first hollow body (2), in the connection area (V) where said first hollow body (2) is to be subsequently connected to said second hollow body (3). Then, the relevant outer wall (2a) of said first hollow body is further enlarged in the aforementioned connection area (V) of the two hollow bodies (2, 3) by means of a hydraulic pressure medium. If a burst pressure is exceeded (Pb), the pressure medium expands in the second hollow body (3) until optional deformation through high inner pressure or connection of said first hollow body (2) to said second hollow body (3) is obtained.
