Abstract

Dispositif de verrouillage (100) axial d’un premier élément tubulaire (20) reçu à ajustement dans un deuxième élément tubulaire (E), le dispositif de verrouillage comprenant un corps (101) tubulaire comportant une gorge (101.2) annulaire externe dans laquelle une bague (102) est montée coulissante selon un axe longitudinal (Y101) du corps entre une position de verrouillage et une position de libération, la bague comprenant une couronne (102.1) ayant une face frontale depuis laquelle s’étendent en saillie axiale des griffes (102.2) d’accrochage externes élastiquement déformables entre un état en saillie radiale du corps et un état escamoté vers l’intérieur du corps, et la gorge du corps comprenant un fond (101.7) conformé pour maintenir les griffes dans leur état en saillie lorsque la bague est en position de verrouillage, et pour autoriser les griffes à passer de l’état en saillie à l’état escamoté lorsque la bague est en position de libération.
