An improved locking device for closing panels, particularly doors or windows, of the type comprising a dead lock and a spring lock biased by spring means to a projecting position relative to the panel as well as a cylindrical safety block, extending through the panel thickness and operatable by a key on either side of said panel, a projection being provided on the cylinder so as to enter, under the pushing action of the key, at least one groove provided on the dead lock tail and to impart thereto a translation movement in and out of a corresponding keeper, said projection driving by means of hinged levers connected to the dead lock the spring lock to the retracted position inside the panel against the action of said spring, wherein the improvement comprises, a driving arm mounted on the one end thereof on the dead lock tail and having a least one groove which coincides accurately with one groove provided on the dead lock tail and into which the cylindrical safety block projection is simultaneously engaged during the rotation thereof by means of the key, in such a way as to impart to said arm a translation movement, said driving arm being connected with the other end thereof to a plurality of locking members which are guided inside the panel, so as to cause the entering into or the release from corresponding keepers under the action of the translation movement thereof.
