The closure device (1) comprises a sleeve-shaped maneuvering part (5) with an inwards converging free mantle end and an essentially cylindrical mantle part (33), the latter being connected to a top containing a central bearing hole for a control and indicator pin part (21). The pin part can be slid into the hole and forms one end of a pin designed to grip inside the neck part (17) of the closure device when in the locking position, via claws at the ends of tongues (25), the claws protruding from a flange in a direction away from the pin. The maneuvering part can be moved along the pin part between a released position where the top is moved up to the free end of the pin part and the claws extend into the diverging mantle part, and a locking position where the free end of the pin protrudes out of the bottom and the claws are pressed into the neck part by the mantle part. The nipple (2) has a rubber body (3) acting as the main seal. |
