A sleeve f or repairing a fluid pipe (), including a rigid or flexible shell () which forms a mold that surrounds at least one defective area () of the pipe. A liquid-state polymerizable material is injected into the mold, which polymerizes and seals the defective area. The sleeve also includes an insert which is made up of several coils of a filiform element (), which is wound into a helix around the defective area of the pipe, before the polymerizable material is injected or infused.

Sleeve with insert for repairing high-pressure fluid pipes

Device for applying at least one active principle, consisting of a material wherein one or several capsules or microcapsules containing the active principle(s) are distributed in a binder having a sponge-like consistency so that the active principle(s) is/are released when pressure is exerted on the material. The device consists of a first part () and a second part (), separated by a tear-off portion (), the capsule or most of the capsules or microcapsules being located in the first part close to the tear-off portion, the first part being detached from the second part by tearing the tear-off portion so as to obtain, at the breakage interface, a surface for applying the active principle(s) contained in the first part when pressure is exerted thereon.
