The subject of the invention is a current distributor comprising a conductive profile which comprises a groove (2) open in the front face of the profile in order to slidably receive a screw head, the groove being delimited by a bottom, two side walls and two front walls which are separated by a distance substantially equal to the diameter of the screw rod. This profile comprises a lower groove (2A) and an upper groove (2B) which grooves are superimposed, the lower groove being dimensioned to receive the head (3) of a hammer screw and the upper groove being dimensioned to receive the head (4 ) of a hex head screw.
