7. The fastening device according to claim 1 , wherein the holding portion in its entirety inclines in the direction of the fastening portion as the holding portion extends from the support portion before the holding portion and support portion are pre-fixed to the lead.

8. The fastening device according to claim 7 , wherein the fastening portion extends from the support portion in an axial direction, the holding portion including a holding bracket that has a lower end for holding the lead which is spaced from the lowermost point of the support portion in the axial direction.

9. The fastening device according to claim 1 , wherein the fastening device is detachably connected to the lead when the fastening device is pre-fixed to the lead.

10. The fastening device according to claim 1 , wherein the support portion is curved, the holding portion including a bracket that is curved in a direction opposite to the curved support portion.

11. The fastening device according to claim 1 , wherein the holding portion has an arm and a holding bracket connected non-rotatably to the arm.

12. The fastening device according to claim 11 , wherein the support portion defines a longitudinal direction in which the lead is to be placed on the support portion, the holding bracket being curved relative to a transverse direction perpendicular to the longitudinal direction.

13. The fastening device according to claim 1 , wherein the holding portion acts to maintain the lead in engagement with the support portion and the holding portion.

14. The fastening device according to claim 1 , wherein the at least one holding portion comprises a pair of holding portions that engage the same lead to pre-fix the lead to the support portion of the fastening device.

15. The fastening device according to claim 1 , wherein the at least one holding portion extends directly from the support portion.

16. The fastening device according to claim 1 , wherein the at least one holding portion and the support portion receive a single lead.

17. A fastening device for a lead, the fastening device comprising:

a support portion having a first side for engaging the lead when the lead is pre-fixed to the fastening device and a second side,

a fastening portion extending from the second side of the support portion for connecting the fastening device to a support; and

a one-piece holding portion extending from the support portion and irremovably connected to the support portion, the holding portion having a portion clamping the lead to the support portion when the lead is pre-fixed to the fastening device, the holding portion being formed by an arm and a holding bracket connected non-rotatable to the arm, the holding portion extending downwardly to a position located on the second side of the support portion when the lead is disconnected from the support portion.

18. The fastening device according to claim 1 , wherein the holding portion is substantially L-shaped.

19. The fastening device according to claim 17 , wherein the holding portion is substantially L-shaped.

20. The fastening device according to claim 17 , wherein the support portion is curved and the holding bracket is curved in a direction opposite to the curved support portion.

21. The fastening device according to claim 17 , wherein the support portion defines a longitudinal direction in which the lead is to be placed on the support portion, the holding bracket being curved relative to a transverse direction perpendicular to the longitudinal direction.

22. The fastening device according to claim 17 , wherein the holding portion acts to maintain the lead in engagement with the support portion and the holding portion.

23. The fastening device according to claim 17 , wherein the at least one holding portion comprises a pair of holding portions that engage the same lead to pre-fix the lead to the support portion of the fastening device.
