The invention provides a safety device for switching appliances formed by the assembly of at least two removable modular elements, namely a switching module and an indirect switching control module which is able to pass from a tripped condition to a set condition by means of a setting member, tripping following a tripping order applied to a tripping member. The control module is fixed to the switching module by means of a screw whose head is only accessible in the set condition of the control module.
