Abstract
Dispositif destiné à fermer le débouché d'un tube et à immobiliser temporairement sous charge des articles contenus dans le tube. Il comporte un organe d'encliquetage 33 engagé dans le tube et un organe de maneeuvre 31 agissant pour accrocher des cliquets 50 de l'organe 33 sur la paroi du tube ou pour les dégager. Un élément de verrouillage 32 verrouille temporairement les organes 31 et 33 pour éviter leur déplacement axial. Application, par exemple, à la fermeture d'un tube contenant des éprouvettes de surveillance à la périphérie d'un coeur de réacteur nucléaire.
