Abstract
The coupling (10) comprises a body (16) suitable for being fitted onto a tube (12) in leaktight manner, and a locking clip (22) that is elastically deformable between a locking configuration in which at least one locking zone (24A, 24B) of the clip can catch on a catch surface (14) of the tube and an unlocking configuration. The clip (22) is disposed over the wall of the body (16), which wall is provided with at least one transverse slot (30A, 30B) through which the locking zone (24A, 24B) projects into the body when the clip is in the locking configuration, and with at least one setback (32A, 32B; 36A, 36B) provided at the end of the slot, a portion of the bottom of said setback forming an unlocking ramp (34A, 34B; 38A, 38B) on which an unlocking zone (35A, 35B; 37A, 37B) can slide in order to cause the clip to go from its locking configuration to its unlocking configuration. The width of the unlocking zone is greater than the width of the locking zone and than the width of the slot, but less than or equal to the width of the setback, said widths being measured axially.
