Abstract
A lid for a pressure cooker has two radially slidable jaws with upstanding lips, respectively. A locking plate can slide transversely outwards from the position shown so that the lips ride along limbs of apertures and are thereafter held, to prevent radial movement, by the plate. The plate is held in its transverse outward position by a plunger (not shown) of a locking valve that is engaged in an aperture in the plate. The plunger is released to fall from an uplifted locking position when pressure in the cooker falls below a predetermined level and to enable the plunger to become slidable along the aperture. This allows the plate to move and unlock the jaws so that the lid can be removed.
