Each catch (12) of the locking finger (11) is mounted in a perfectly symmetrical way on the end of the rotary finger which can rotate under the action of a control rod (14) held by nuts (15). The catch allows positive security of locking or unlocking by becoming housed in a recess (22) provided on the flange (9) of the door (3). Application to freeze-drying tanks. <IMAGE>
