A wire (8) is tensioned on the basic component (1) of the welding rail. The tension is obtained by securing devices (10) fitted in the end sections of the basic component (1) of the welding rail. Each securing device (10) comprises a rocker (10) which can pivot about a pin (23) and is fitted with means (26) to secure one of the end sections (9) of the wire (8). These holding means (26) are in a section of the rocket (20) on one side of the pin (23). Each securing device (10) also comprises a device (40) for exerting pressure on that section of the rocker (20) lying on the opposite side of the pin (23). The pressure device (40) has a longitudinal bracket (45) which can be screwed to a support (41). One of the end sections (48) of said bracket (45) acts on the rocker (20) and its other section (49) is supported by a pressure spring (50). |
