The present application relates to a lid (4) for a pressure cooking appliance (1) the lid designed to be placed and locked on a cooking vessel (2). The lid (4) comprises at least one jaw (5) mounted to move radially between a locking position and unlocking position. Said at least one jaw (5) is substantially of channel section, with a top face (10) for bearing on the lid (4), a front face (11), and a folded-under bottom face (12) designed, when in the locking position, to come into contact with the underside of a rim (3) of the cooking vessel (2). The at least one jaw (5) includes a substantially central setback (15) extending in the front and bottom faces (11, 12) thereof so as to define two locking wings (16, 17). The invention also provides a pressure cooking appliance fitted with the lid (4).

The invention claimed is: 1. A lid (4) for a pressure cooking appliance (1), the lid designed to be placed and locked on a cooking vessel (2), said lid (4) comprising: at least one jaw (5) mounted to move radially between a locking position and unlocking position, said at least one jaw (5) being su
The invention claimed is: 1. A lid (4) for a pressure cooking appliance (1), the lid designed to be placed and locked on a cooking vessel (2), said lid (4) comprising: at least one jaw (5) mounted to move radially between a locking position and unlocking position, said at least one jaw (5) being substantially of channel section, with a top face (10) for bearing on the lid (4), a front face (11), and a folded-under bottom face (12) designed, when in the locking position, to come into contact with the underside of a rim (3) of the cooking vessel (2); wherein said at least one jaw (5) includes a substantially central setback (15) extending in the front and bottom faces (11, 12) thereof so as to define two locking wings (16, 17). 2. The lid according to claim 1, wherein the top bearing face (10) comprises two lateral top faces (10A, 10B) situated in the locking wings (16, 17), each of said lateral top faces (10A, 10B) being connected via an associated connection face (10C) to a central top face (10D) situated in register with the central setback (15), said central top face (10D) being raised relative to the two lateral top faces (10A, 10B). 3. The lid according to claim 2, wherein the connection face (10C) connects progressively firstly to the lateral top faces (10A, 10B), and secondly to the central top face (10D). 4. The lid according to claim 3, wherein the progressive connection of the connection face (10C) takes place via two opposite connection radii of values R1 and R2 lying in the range 10 mm to 40 mm and leading respectively to the lateral top faces (10A, 10B) and to the central top face (10D). 5. The lid according to claim 2, wherein the lateral top faces (10A, 10B) slope at an angle α relative to the horizontal, the slope being oriented in such a manner that the outermost portions (20) of said faces furthest from the axis of symmetry YY' of the jaw (5) bear against the lid (4). 6. The lid according to claim 5, wherein the angle of inclination α of the lateral top faces (10A, 10B) lies in the range 0.5�� to 1.5��. 7. The lid according to claim 1, wherein each of the two locking wings (16, 17) includes a bottom face (12) that is folded under and substantially planar. 8. The lid according to claim 4, wherein the front face (11) connecting the bottom face (12) of each wing (16, 17) to the central top face (10D) terminates towards the setback (15) in an inclined edge (21) whose top end (22) is closer to the axis of symmetry (YY') of the jaw (5) than is its bottom end (23). 9. The lid according to claim 8, wherein each of the two locking wings (16, 17) has a front face (11) which connects with the connection face (10C) or the central top face (10D), at the level of the central top face. 10. The lid according to claim 1, further comprising two radially-opposite jaws (5). 11. The lid according to claim 1, wherein the lid (4) is circular and each jaw (5) defines a circular arc subtending an angle at the center that is equal to or greater than 90��. 12. A pressure cooking appliance comprising: a cooking vessel; and a lid configured to be placed and locked on the cooking vessel, the lid comprising: at least one jaw mounted to move radially between a locked position and an unlocked position, the at least one jaw being substantially of channel section and having a top face for bearing on the lid, a front face, and a folded-under bottom face designed, when in the locked position, to come into contact with the underside of a rim of the cooking vessel, the at least one jaw further including a substantially central setback extending in the front and bottom faces thereof so as to define two locking wings.
