Abstract
A closing device, particularly for closing channels conducting pressure medium in a valve receiving body, has a rotationally symmetrical closing element (6) that is fastened in a seating bore (1) of a housing (14), having a calking site (2) that is provided on the circumference of the closing element (6) and that permanently fixes the closing element (6) in the housing (14) as a result of the plastic displacement of housing material. The seating bore (1) includes a transition area in the form of a bore step (4) between the calking site (2) and a centering cone surface (3). The bore step is recessed into the seating bore (1) by the plastic displacement of the housing material in the form of a bulge surrounding the closing element (6).
