Claim:
1. A centralised control mechanism, with integrated safeties, in combination with a first closed space for the sealed transfer between the first closed space and a second closed space, the first closed space comprising a first flange and a first door, the first flange can be securely attached to a second flange of the second closed space by a first bayonet connection, and a first door normally plugging an opening delimited by the first flange wherein the first door can be securely attached to a second door of the second closed space by a second bayonet connection, the control mechanism comprising: a movable control member installed on the first flange such that it is able to move between a closed position and an open position, passing through an intermediate locking position, a system of ramps interposed between the control member and the first door, in order to separate the first and second doors from the first and second flanges when the control member moves from its locking position to its open position, a first bolt assembly normally blocking the control member in its closed position when in a locked state, and which is automatically placed in an unlocked state by the presence of the second door against the first door, a second bolt assembly normally blocking the control member in its closed position when in a locked state, and which is automatically placed in an unlocked state when the second flange is securely attached to the first flange by the first bayonet connection, a third bolt assembly which is normally in an unlocked state when the control member is in its closed position, and which is automatically placed in a locked state so as to block the first bayonet connection in a condition of secure attachment of the first and second flanges when the control member is moved between its locking position and open position, a fourth bolt assembly, which is normally in an unlocked state when the control member is in its locking position, and which is automatically placed in a locked position to prevent the control member from returning to its locking position, after the control member has been moved towards the open position and after the first and second doors are separated from the first and second flanges by the cooperation between the control member and the system of ramps, and a protective bolt assembly which is normally in an unlocked state in the closed position and in the open position of the control member, and which blocks the control member in a locked state when the second flange is not securely attached to the first flange between the time when the second bolt assembly is in the unlocked state, and before the time when the third bolt assembly blocks the first bayonet connection, so as to prevent the first door from opening.
