An electric connection box having a protecting function, comprising:

• a box body;
• a protecting function unit including a stationary unit formed integrally with said box body, wherein said stationary unit has at least an output terminal, an input terminal and a pair of terminal protecting contacts;
• and
• a movable member attached removably to said stationary unit, said movable member has an input connecting terminal and an output connecting terminal, said movable member being removably attached to said stationary unit in a first attached position in which said input connecting terminal contacts said input terminal and said output connecting terminal contacts said output terminal to form a first electrical path and said pair of terminal protecting contacts contact with one another in a first contact position, the movable member having bottom and side faces wherein
• a supply of an electric power from a vehicle-mounted power source to an electric load is interrupted by removing said movable member from said stationary unit, and wherein said stationary unit is a mounting recess arranged on an upper side of said box body for housing said movable member so that the movable member is held on its bottom and side faces by said mounting recess.
