A closure, automatically, on the one hand with a compression spring and closing with a pressure medium, in the case of which the closing ring is a standardised part and is guided by means of a column guide. Closing parts on closures were until now generally guided using tube-like hollow bodies, the passage at the terminating point of the closure being as narrow as the hole in the hollow body. In contrast, the column guide has a passage at the terminating point of the closure which is larger by the size of the free space between the columns. The closure is equipped with a ball-detent connection of known type, in the case of which, however, the compression spring of the operating sleeve does not stop in the normal manner on a collar of the closure body but is supported on a stop ring which is fitted on the closure body. It is thus possible to save material for the closure body.
