 a base;   a separator element projecting from the base; and   a pusher element adapted to cooperate with the separator element and provided with a planar end adapted to be directed towards the base,   a washer provided with a pass-through opening configured to be fitted onto the separator element, so as to be interposed between the pusher element and the base;   wherein the base comprises two flaps arranged at opposite sides with respect to the separator element, wherein the flaps are tilted between each other and form a dihedral angle lower than the straight angle opposite to the separator element; and   wherein the washer comprises at least a first planar surface directed towards the pusher element and a second surface directed towards the base, wherein the second surface comprises at least a pair of support planes arranged on opposite sides with respect to the pass-through opening, wherein the support planes of the pair of support planes are tilted between each other and form an additional dihedral angle lower than the straight angle.   
     
     
         2 . The device according to  claim 1 , wherein the dihedral angle substantially ranges from 110° to 85°. 
     
     
         3 . The device according to  claim 1 , wherein the separator element rises along a direction that is parallel to a plane bisecting the dihedral angle and orthogonal to a vertex edge of the dihedral angle. 
     
     
         4 . The device according to  claim 1 , wherein the flaps are at least partially flexible, for example elastically, and/or rotatably coupled to the separator element at a hinge axis parallel or coincident with a vertex edge of the dihedral angle formed therefrom. 
     
     
         5 . The device according to  claim 1 , wherein the pusher element is movably associated to the separator element, at least approaching from the base along a movement axis laying on a plane bisecting the dihedral angle and orthogonal to a vertex edge of the dihedral angle. 
     
     
         6 . The device according to  claim 1 , wherein each of the flaps comprises one first surface internal with respect to the dihedral angle and one oppo-site second surface external to the dihedral angle that is substantially parallel to the first surface of the same flap, the separator element comprises a base end joined to the base at a peak edge of the base wherein the second surfaces of the flaps converge. 
     
     
         7 . The device according to  claim 1 , wherein at least a portion of the separator element is connected to the base in a frangible manner, by a pre-established fracture line or section. 
     
     
         8 . The device according to  claim 1 , wherein the additional dihedral angle formed by the support planes of the second surface of the washer ranges from 110° to 85° and/or is congruent to the dihedral angle formed by the flaps of the base. 
     
     
         9 . The device according to  claim 1 , wherein the first surface is configured to come into contact with the planar end of the pusher element and, preferably is orthogonal to a pass-through axis of the pass-through opening. 
     
     
         10 . The device according to  claim 1 , wherein the separator element comprises a threaded stem to which the pusher element can be screwed. 
     
     
         11 . The device according to  claim 1 , wherein the pusher element comprises a pressure wedge. 
     
     
         12 . The device according to  claim 1 , wherein the washer comprises a supporting surface directed towards the pusher element, wherein the supporting surface is planar and parallel to the first surface, the pusher element being configured such that its planar end can selectively come into contact with the first surface and the supporting surface of the washer.
