Abstract
A closure device for closing an opening in a wall in a vacuum-tight manner has a valve plate, which by way of a connecting device is connected to a valve rod, for closing and exposing the opening. The connecting device has a swivel head of which at least portions of the external surface are of a spherical configuration and which is disposed in a receptacle space of a joint body. For blocking a rotation of the swivel head about the longitudinal axis of the valve rod, at least one projecting stud, that is disposed on the swivel head or joint body, protrudes into an assigned groove which is disposed in the other one of these two parts and which in a central position of the connecting device extends in a plane that lies parallel to the longitudinal axis of the valve rod.
