Patent ID: 8445784

Claim:
A protection device comprising: a mechanical protection sheath ( 20 ); and a thermal protection end-piece ( 30 ) mounted at one end ( 21 ) of the mechanical protection sheath ( 20 ), said mechanical protection sheath ( 20 ) comprising a tubular textile structure that is deformable by compression in a lengthwise direction (X) of the mechanical protection sheath ( 20 ) and said textile structure having in a lengthwise compression area ( 24 ) an expanded sheath portion ( 25 ) adapted to cooperate with one end ( 32 ) of the thermal protection end-piece ( 30 ) by being turned back on the expanded sheath portion, wherein said mechanical protection sheath ( 20 ) is deformable between a position of unstable equilibrium in which said expanded sheath portion ( 25 ) is turned back on the expanded sheath portion and retained by one end ( 32 ) of the thermal protection end-piece ( 30 ), and a rest position in which said mechanical protection sheath ( 20 ) is aligned with said thermal protection end-piece ( 30 ) and the mechanical protection sheath ( 20 ) is movable from said position of unstable equilibrium to said rest position by elastic return of said mechanical protection sheath ( 20 ) to said rest position.
