Abstract

See full text

The invention relates to a flexible pipe including a hose for carrying hydrocarbons and a connection endpiece at the end of the hose. The hose has an inner carcass, a sacrificial sublayer, and a sealing barrier. The endpiece has a tubular body in which the inner carcass, the sacrificial sublayer, and the sealing barrier are inserted. A sealing bush is crimped onto the sealing barrier. The endpiece includes a retaining ring secured to the inner carcass. A lock advantageously opposes axial displacement of the retaining ring in the direction for dissembling the hose from the endpiece.
