Abstract

A sealing device is disclosed comprising a least one sealing leaf maintained axially in position by a retaining bracket which comprises a first end bearing on the sealing leaf and a bent-back second end engaged in a groove in a structural element. The sealing leaf is preferably retained radially in position by lugs which are bent so as to engage below lugs provided on the retaining bracket. When the sealing device comprises at least two adjacent sealing leaves placed edge to edge, the device also comprises a cover sheet so disposed between the sealing leaves and the retaining bracket as to cover the joint between the two adjacent leaves.
