A device for connecting a conductor to a terminal, including a screw slidable inside the terminal of an apparatus, the screw having a first head portion to be actuated and screwed into a head nut and a second body portion to be screwed into a body nut mounted in a casing of the apparatus, the screw being mobile between an open position in which the screw is screwed only into the head nut so as to allow the introduction of a tag into the terminal between the screw body and a pad and a closed position in which the screw is screwed into both the body nut and the head nut so as to clamp the tag between this screw body and the pad. This device includes a device for synchronizing the threads respectively associated with the screw body and the screw head, this device ensuring automatic returning of the screw body towards the screw head when the screw body is brought into contact with the body nut during screwing until synchronization of the two threads.
