The invention relates to a locking device for fixing a lid (1) to the opening (8) of a pressure vessel, comprising at least two locking segments (5) that can be moved crosswise relative to the axis of the opening (8), said locking segments having projecting elements (6) and groove-shaped recesses in their periphery that in closed position cooperate with recesses (7) or projecting elements in the edge of the opening, wherein the displacement drive mechanism (4) of the segments (5) is hinged to the segments (5) and at least one site of action arranged on the lid (1) or on a component (3) that is connected to the lid (1). According to the invention, the segments (5) arranged in peripheral direction of the lid (1) are supported in an articulated manner on the lid (1) by means of a pivoting arm (16) that is separate from the displacement drive mechanism (4).

L'invention concerne un dispositif de verrouillage utilisé pour fixer un couvercle (1) sur une ouverture (8) d'un contenant sous pression, ce dispositif comprenant au moins deux segments de verrouillage (5) pouvant être déplacés transversalement par rapport à l'axe de l'ouverture (8), lesquels présentent, sur leur périphérie, des saillies (6) et des évidements en forme de rainures qui, en position de fermeture, coopèrent respectivement avec des évidements (7) ou des saillies formés sur le bord de l'ouverture. Le dispositif de décalage (4) des segments (5) est articulé aux segments (5) et à au moins un point d'application de force disposé sur le couvercle (1) ou sur une pièce constitutive (3) reliée audit couvercle (1). Selon l'invention, les segments (5) disposés dans le sens circonférentiel du couvercle (1) reposent, de façon articulée, contre le couvercle (1), par l'intermédiaire d'un bras oscillant (16) séparé du dispositif de décalage (4).
