Abstract
An interchangeable member (38), such as a glove, collar or bag, is fixed in a cell flange with the aid of a supporting ring (36) formed of two sections bearing an extremity flange (50) of the member (38) and also with the aid of a safety ring (72) secured to the flange (16) and to the supporting ring (36) by two bayonet links and rotational immobilized by two blocking members (82, 78) with respect to the flange and the supporting ring. A mounting tool (100) is equipped with an indexing part (136) which makes it possible to retract the blocking members when the safety ring is mounted.
