A device for coupling an end of a hose to a member, comprises a body provided with an internal channel opening out into a chamber having quick-connection elements for connecting the end of the hose to the channel. The quick-connection elements comprise a washer with teeth disposed in the chamber and associated with a tubular disconnection pusher which is mounted to slide inside the chamber and which possesses a drive end projecting outside the body, and an opposite end for lifting the teeth. The device comprises protection elements for protecting the connection, which include a sleeve () possessing axially in succession: a connection portion () for connection to the body extending around the drive end; and a hose guide portion () which is secured to the connection portion via an end opposite from the body and which extends beyond the drive end coaxially with the internal channel.

Connecting device comprising means for instantaneous connection of a pipe end to a member and means for protecting the connection

The invention provides means for connecting a pipe to a tubular body having an end arranged to receive an end of the pipe. The connection means comprise a sleeve subdivided into first and second portions in axial succession that are provided with means for connecting said portions in leakproof and releasable manner respectively to the end of the tubular body and to the pipe. The means also comprise a removable abutment ring provided with means for locking it axially on the pipe set back from the end thereof to constitute an abutment shoulder on engagement of the pipe in the tubular body and an axial abutment shoulder between the second portion of the sleeve and the pipe.
