<p>The invention relates to a flexible sleeve (1) arranged to be connected to at least one rigid duct (2a, 2b), said sleeve including at least one end arranged to be fitted onto an end of said duct. The end of the sleeve includes a peripheral groove (3a, 3b) formed in the inner surface thereof and arranged for receiving, when said end is slipped onto an end of said duct, a complementary peripheral bead (5a, 5b) arranged on the outer surface of said end, and the inner perimeter (4a, 4b) of said sleeve end is smaller than the outer perimeter (6a, 6b) of the end of said duct such that the reception of said bead in said groove and that the difference between the perimeter of the inner surface of said sleeve end and that of the outer surface of said duct end ensures a connection between said sleeve and said duct that is sealed to the material to be conveyed by the sleeve and the duct.</p> |
