SUBSTANCE: vessel includes the first subcylinder (4), the second subcylinder (6), pre-stress device (8) and fastening element (16). The first and the second subcylinders (4, 6) are axially connected with possibility of forming cylindrical casing (2) to contain high-pressure medium. The first subcylinder (4) on the external wall is equipped with the first seat (22) to place the first part (24) of fastening element (16), and the second subcylinder (6) on the external wall is equipped with the second seat (26) to place the second part (28) of fastening element (16). The latter is inserted into the first and the second seats (22, 26). Fastening element (16) and the first, and the second seats (22, 26) are arranged so that fastening element (16) and the first, and the second seats (22, 26) can interact with possibility of preventing disconnecting axial movement between the first and the second subcylinders (4, 6). Pre-stress device (8) is arranged around an enveloping surface of cylindrical casing (2) so that cylindrical casing (2) is radially pre-stressed and so that fastening element (16) is fixed in the first and the second seats (22, 26).
