Abstract: The invention relates to a food pressure cooking appliance including a bowl and a lid intended to be locked relative to the bowl to form with the latter a cooking chamber adapted to rise in pressure. The appliance includes bayonet locking means forming first and second series of protrusions that are integral with the envelope of the lid and the envelope of the bowl, respectively, and that are intended to cooperate with each other to ensure the locking of the lid relative to the bowl. Each protrusion of at least one of the series consists of a volume element that has opposite convex and concave faces and is formed by a localized radial deformation of the corresponding envelope.
