Abstract
This invention relates to a quick connection of a tube capable of being fitted in a connector, said tube presenting, at a determined distance from its end, a shoulder, whilst the connector comprises an O-ring intended to come into contact with the tube in the zone located between its end and the shoulder. A member for locking the tube is mounted in the connector, said member being axially immobilized with respect to the connector and elastically deformable in the radial direction between an inactive configuration and an active configuration in which it abuts on the shoulder. A bush is mounted to slide in the connector between a first position and a second position remote from the first towards the inside of the connector, said bush presenting a stop disposed on the path of the shoulder of the tube and ensuring, in its first position, hold of the locking member in its inactive configuration, whilst the locking member is released when the bush is in its second position.
