Then, the locking band is lowered around the skirt 33 to constrain the fastening means 332 under the shoulder of the neck and lock in this position.

Thus, a suitable traction or torque makes it possible to break the bridges 351, which makes it possible to separate the lugs 331 from the remainder of the ring. It may be noted that three material bridges 351 are formed solely by two windows 35, since the end bridges are formed in cooperation with the slots 333.
