Abstract: This device for locking in a rack the front face (2) of a drawer (1) for electronic board(s) comprises a bolt (9) mounted so as to slide on the front face between a position locking it in a strike plate (11) carried by the rack and an unlocking position, and a pivoted lever (10) adapted to displace the bolt (9) between the locking and unlocking positions when it is turned respectively between a position in which it is substantially folded down along the front face (2) and a gripping position in which it projects with respect to the front face. The lever (10) is pivoted on the bolt (9) and is movable in translation together with the latter, and the lever (10) and the front face (2) have complementary members which cooperate to displace the bolt (9) and the lever (10) in translation when the lever is turned between the folded-down position and the gripping position.
