The invention relates to an electronic labeling system consisting of a rail (1) and an electronic display label (20) and a device for the power supply of the label, the rail (1) having two face-to-face wings (3 and 4) extending on a longitudinal direction, each of said wings (3 and 4) having a longitudinal groove (12) on its median region, the electronic label having on one of the two opposite faces (23 and 124) a longitudinal rib (26 and 126) adapted to be inserted into the groove (10) of one of the wings (4) of the rail (1), while on the other opposite face (24 and 123), the electronic label (20 and 120) has at least one movable pin (30 and 130) which snaps into the groove (12) of the other wing (3) of the rail (1) and at least one recess (27 and 127) wherein a ferromagnetic core (29 and 129) is provided, the movable pin (30 and 130) which is pushed into the recess (27 and 127) cut on the surface (24 and 123) of the label, rests on the ferromagnetic core (29 and 129) which can be displaced in the recess (27 and 127) by the magnetic force, in order to retract the pin (30 and 130) and to release the label (20 and 120).
