ABSTRACT:
A door fixture to be fastened to a frame of an isolator includes a door and a double bayonet closure with two bayonet locks for reciprocally transferring the isolator from a first state, in which the door, which opens from inside the isolator, is open and detached from the isolator frame and a container flange surrounding a container is sealingly locked to the isolator frame, and a second state, in which the door is shut and sealingly locked to the isolator frame and the container flange is detached from the isolator frame, there being provided a first safety device, which allows the door to be opened only when a container flange of a container is sealingly locked to the isolator frame, and a second safety device, which allows for the removal of the container flange from the isolator frame only when the door is sealingly locked to the isolator frame.
