Abstract

L'invention concerne un dispositif pour bloquer une unité de maintien et de centrage (10) sur une station de traitement (8) d'un dispositif de traitement de contenant (1), comprenant un support (21) permettant de raccorder le dispositif (20) à la station de traitement (8), et une unité de blocage (22) permettant de bloquer sur la station de traitement (8), de manière libérable, une unité de maintien et de centrage (10) acheminée dans une direction de réception (AR) de la station de traitement (8). Le dispositif selon l'invention présente également une unité de réception (23) permettant de raccorder l'unité de blocage (22) au support (21). L'unité de réception (23) peut être déplacée sur le support (21) par l'intermédiaire de moyens d'entraînement (24) parallèlement à la direction de réception (AR).
