A ratchet wrench with interchangeable sockets is of the type incorporating an elongated casing formed of two half-shells in which a hub is positioned inside which slide a finger, a ratchet and an assembly of front, median and rear toothed wheels and their associated toothed pinions and a rack. The wrench includes, in addition, a slide arranged longitudinally in the casing meshing onto the rear wheel by the rack to drive the rear wheel in rotation and a pusher protruding from the casing linked to the slide to drive the slide in translation. The device ensures a first tilting of the rack onto the rear wheel and a second tilting of this rack to release the rear wheel.
