6. Binding device according to claim 1 , wherein the base ( 11 ) of the support ( 9 ) is provided with two upright arms ( 19 ) on the side oriented away from the open side of the U-shaped profile ( 10 ).

7. Binding device according to claim 1 , wherein the wings ( 22 ) are made of an insulating material or that at least the section of the wings ( 22 ) that can come into contact with the magnet ( 17 ) is provided with a casing of an insulating material.

8. Binding device according to claim 1 , wherein the binding device ( 1 ) is provided with a guide ( 19 ) for the movement of the magnet ( 17 ).

9. Binding device according to claim 2 , wherein the wings ( 22 ) extend over at least a limited distance from the free end ( 23 ) parallel to the base ( 11 ) of the support ( 9 ).

10. Binding device according to claim 2 , wherein the wings ( 22 ) consist of two parts, i.e. a first part ( 25 ) that extends from the support ( 9 ) and is oriented away from the base ( 11 ) of the support ( 9 ) and a second part following therefrom ( 26 ) that extends parallel to the base ( 11 ) of the support ( 9 ).

11. Binding device according to claim 3 , wherein the wings ( 22 ) consist of two parts, i.e. a first part ( 25 ) that extends from the support ( 9 ) and is oriented away from the base ( 11 ) of the support ( 9 ) and a second part following therefrom ( 26 ) that extends parallel to the base ( 11 ) of the support ( 9 ).

12. Binding device according to claim 2 , wherein the wings ( 22 ) extend over the entire length of the support ( 9 ).
