The invention relates to elements comprised in high-pressure receptacles, especially a device for sealing the tube of an inner sheath in the neck of a high-pressure receptacle, wherein a body (1) made of a composite material is internally lined with a sealed sheath (6). The sheath consists of a tube (7) extending in an axial channel (8) of the neck (4). An annular cavity (17) is formed between the tube (7) and the connection (10). The ends thereof are closed by the flange (11) of the connection and by the collar (14) of the neck (4). The cavity is filled with a sealing product (18) having an external, radial effect upon the tube and making it tighter as a result of axial compression arising from displacement of the flange of the connection (10). The invention can be used in the manufacture of bottles such as those used by mountain climbers, skin divers, aircraft pilots, rescuers, firemen. |
