This invention solves the problem of clamping the material for electrical installation. The clamping force pressing the wire towards the supporting construction profile through fireguard base plate is exerted by a wound binding tape /9/ via arresting-winding part, consisting of a body /1/ with hole /8/ for anchoring one end of the binding tape /9/ and bended arms /2/ serving for pressing the wound part of the binding tape /9/ when arresting, with holes /3/ for the screw /4/ with a groove /5/ the binding tape /9/ and fan plates /6/ having the arresting effect against bad rotation of the winding screw (4) in the time of tightening the nut /7/.<IMAGE>
