Abstract
A quick connector is provided for connecting a tube inserted into a connection element. The tube includes an annular swell spaced at a distance from its end. The connector housing of the connection element is provided with a locking member and locking ring elastically deformable in a radial direction between a free state configuration and an unlocking configuration. The outer periphery of the connector housing has two cylindrical parts separated by an axial stop. The locking ring abuts the axial stop. A locking lug is connected to the locking ring and includes a front ramp with a transverse slot. A spacer deforms the locking lug in a radially outward direction to the unlocking configuration. When the tube is fitted in the connection element, the front ramp of the locking lug cooperates with the swell of the tube to move the lug apart. When the tube has been fitted in the connector and the slot is at the axial level of the swell, the locking lug approaches its free state configuration. The swell penetrates the slot and lug will adopt a locking configuration. The spacer can be activated without a tool to disconnect the tube from the connector.
