ABSTRACT:
The device is applicable to the connection of two enclosures, each having a door closing and opening formed in a flange. One of the doors supports a rotary control member having three series of slots forming cams. V-shaped levers articulated to the doors simultaneously cooperate with slots and with the bolts in order to displace the latter between locking and unlocking positions under the action of rotating the member. The configuration of the slots makes it possible to control the locking of the doors to one another and to the flanges in a sequential manner. Preferably, the bolts are inclined in the direction aiding sealing.
