Abstract: The invention relates to a cooking vessel (1), particularly a steam pressure cooker, comprising a pot-like container and a lid (3) provided for pressure-tight sealing of the container. The container displays a circumferential, outwardly bent or flanged pot edge. Clamping jaws (6) are provided on the lid (3), which serve as locking segments and can be moved into an open or locked position parallel to the plane of the pot edge (5), where the clamping jaws (6) reach under the pot edge in locked position. The invention is characterized by the fact that the clamping jaws (6) each extend over almost half the circumference of the lid (3) and that the clamping jaws (6) are mounted in a manner permitting pivoting movement about a pivot (12) extending parallel to, and at a distance from, the longitudinal centre line of the container (FIG.
