A hood for extracting cooking fumes comprising: - a box-like housing having a front side with an opening formed therein for extracting cooking fumes; - suction means placed in said box-like housing for channeling the cooking fumes through said opening; - a covering panel placed outside said box-like housing and designed to face said opening; - at least one hinge, connected to said box-like housing and to said panel to allow a pivotal movement of said panel relative to said box-like housing, said panel being configured to switch between a closed configuration, in which it is placed adjacent to said opening, and an open configuration in which the interior of said box-like housing can be accessed through via said opening; said hinge comprising a stationary element joined to the box-like housing, and a movable element attached to said panel, said movable element being adapted to rotate about an axis of rotation ("R") to switch said panel from the closed configuration to the open configuration; said movable element being configured to slide relative to the stationary element to lock the pivotal movement of the panel in the open configuration. characterized in that - said movable element comprises a guide comprising a rotating section and a locking section, opposite to the rotating section and separated therefrom by the first predetermined length; - said stationary element comprising a pin placed within said guide, said guide being adapted to pivot relative to said pin engaging the rotating section to reversibly switch the panel from the closed configuration to the open configuration, said guide being also adapted to slide relative to said pin moving from the rotating section to the locking section and vice versa to lock or unlock the pivotal movement of the panel when said pin respectively engages or disengages the locking section when said panel is in the open configuration, said stationary element comprising a support attached to the box-like housing, said pin extending away from the support and having one end distal from said support, said pin comprising a body, said locking section having a shape that matches the shape of the body to prevent undesired rotation of the guide relative thereto when the pin engages the locking section. - a box-like housing having a front side with an opening formed therein for extracting cooking fumes;
