A safety locking coupling assembly in which pull rings on the female coupling unit of a male coupling unit/female coupling unit assembly serve both to release the coupling assembly and to maintain the coupling assembly locked against unintentional disconnection. The pull rings are attached to cam arms which engage the male coupling unit to lock the coupling assembly and are disengaged from the male coupling unit to release the coupling assembly. In the locked condition of the coupling assembly, the pull rings abut against ears on the housing of the female coupling unit to oppose unintended movement of the cam arms from the locked position of the cam arms to the released position of the cam arms. Upon intentional removal of the pull rings from abutment with ears by an operator and pulling on the pull rings, the cam arms can be moved from the locked position of the cam arms to the released position of the cam arms to disconnect the coupling assembly.
L'invention porte sur un accouplement de sûreté dans lequel des anneaux de traction disposés sur la partie femelle de l'accouplement mâle/femelle servent soit à libérer l'accouplement, soit à le maintenir verrouillé vis à vis des déconnexions accidentelles. Les anneaux de traction sont fixés à des bras à came s'engageant dans la partie mâle pour verrouiller l'accouplement et s'en dégageant pour le libérer. A l'état verrouillé de l'accouplement, les anneaux de traction butent contre des oreilles attenant au logement de la partie femelle et s'opposent aux mouvements non intentionnels des bras à came. Lorsqu'un utilisateur désire écarter les anneaux de leur position de butée sur les oreilles, et les soulever, il fait passer les bras à came de la position de verrouillage à la position de déverrouillage, ce qui déconnecte l'accouplement.
