Device for coupling a rigid male endpiece to a flexible female pipe, and production method therefor

A coupling device suitable for connecting a rigid male endpiece to a flexible female pipe, the device comprising:

• a sleeve suitable for gripping the pipe and axially locking the endpiece, the sleeve having a radially inner part configured to surround at least one annular seal, said at least one annular seal being configured to bear on the endpiece,
• a socket comprising a tubular portion which is configured to be gripped by the pipe and which includes a collar at one of its ends, said collar comprising a radial step and a tubular axial end portion, said radial step having a radial step height and that extending radially from said tubular portion to said tubular axial end portion, said tubular axial end portion being mounted radially inside said radially inner part and comprising a cylindrical outer surface in contact with said radially inner part, said tubular axial end portion further including a cylindrical inner surface forming a bottom of an annular groove, said at least one annular seal comprising a cylindrical outer surface in contact with said radially inner part, said tubular axial end portion further including a cylindrical inner surface,
• an assembly that is configured to mechanically assemble the sleeve to said collar, the assembly comprising a continuous circumferential protuberance formed in a single piece with the sleeve,
• wherein said protuberance protrudes inwardly from said radially inner part so as to bear against said radial step, over a majority of said radial step height.
