Abstract
The seal comprises first and a second coaxial sleeve disposed around each other while being retained relative to each other. Each sleeve is formed by a strip wound on itself whose ends are configured to cooperate together via a sealing arrangement by allowing a reduction in the diameter of the sleeve. The sealing arrangements of the two sleeves are angularly offset. The clamping device comprises a clamping collar with a belt inside which the seal is disposed while being retained axially relative to the collar.

A seal comprising a first and a second coaxial sleeve disposed one around the other while being retained relative to each other, each sleeve being formed by a strip wound on itself whose ends are configured to cooperate together via a sealing arrangement allowing a reduction in the diameter of the sleeve, the sealing arrangements of the two sleeves being angularly offset, at least one of the first and second sleeves has at least one squeezing lug, under which one edge on the other one of the first and second sleeves is squeezed.
A clamping device comprising a collar comprising a belt able to be clamped by reduction of a diameter thereof, and a seal disposed inside the belt while being retained axially relative to the collar, the seal comprising a first and a second coaxial sleeve disposed one around the other while being retained relative to each other, each sleeve being formed by a strip wound on itself whose ends are configured to cooperate together via a sealing arrangement allowing a reduction in the diameter of the sleeve, the sealing arrangements of the two sleeves being angularly offset and the clamping device being configured to arrange an annular space allowing the insertion of an annular object between the seal and the belt.
A tube clamping assembly, comprising a collar, a seal and a tube, the collar comprising a belt able to be clamped by reduction of a diameter thereof, the seal being disposed inside the belt while being retained axially relative to the collar, the tube comprising an end able to be inserted in an annular space arranged between the seal and the belt.
