A gripper for a removable lid of a kitchen utensil is provided, which can be fixed to a top of a lid through the action of a magnet on a magnetic component. The gripper comprises a base plate and an operating member that can move relative to the base plate between a magnetizing position in which the force exerted by the magnet on the magnetic component allows the gripper to be secured to the top, and an isolating position in which this force is not strong enough to secure the gripper to the top.
