       6 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 3 , wherein the second of the arms is semi-flexible due to the decrease of its thickness. 
   
   
       7 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 3 , wherein the second arm is united to the first arm of said upper section and to said lower section of the device by means of a thinned zone that acts as a hinge. 
   
   
       8 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 7 , wherein the second arm has in its free end, connection means attached to the connection means of the first arm. 
   
   
       9 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 2 , wherein the connection means in both arms have a hook form. 
   
   
       10 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 3 , wherein the device is attached first to the spacer by means of the connection means. 
   
   
       11 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 10 , wherein the attachment is done due to the projections in the first rigid arm. 
   
   
       12 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 11 , wherein the second of the arms, semi-flexible, moves towards the first connected arm, bending at the hinge zone that unites it with the lower section and the other arm. 
   
   
       13 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 12 , wherein the second of the arms is attached co-operable with the first arm connected to the spacer, and hold by means of connection means. 
   
   
       14 . A device for the positioning and fixation of structural elements of reinforcement for concrete that is attached to a spacer or conventional lateral spacer according to  claim 3 , wherein additionally have a “horizontal” projection from the body of the device outwards, said projection has a flat surface downward oriented and this flat surface is coplanar with the most distant radial point of the spacer or lateral spacer that is attached to the device.
