A deformable annular sealing joint (4) is placed between the fixing ring and the support. A holding ring (5) holds the joint against the support. The support includes a set of holding corners for holding the support on the partition. The holding ring includes semicircular portions (5a, 5b) that are assembled to form a ring. The fixing ring is configured to tighten the annular joint on the pipe. |
