The invention relates to a rail clamp in the form of two parts curved in the form of a C and inter¬ connected by a tie loop. Such rail clamps are used for exerting a vertically downward effort on a rail bar. Under certain conditions it may occur that the rail is exposed to a verticall upward force, for example, during repairs of the ballast bed. In this case the.-resilient force of the clamp may be exceeded. In order to avoid breakdown of the lamp under such conditions a recess may be provided in the housing accomodating the clamp for blocking the parts of the C-shaped clamp.

The invention has for its object to provide a cheaper solution.

According to the invention this is achieved in that the end portions of said C's are provided with fingers and the tie loop has a lock-like portion for receiving at least one of said fingers. The two other fingers block the clamp in a horizontal direction against the housing.

The cross-section of the lock-like portion substantially corresponds to two of said fingers. The lock¬ like portion is located substantially in the centre of the tie loop portion.

The invention will be explained with reference to the drawings.

Figύre 1 is a perspective view of a rail clamp in accordance with the invention and

Figure 2 is a perspective view of a rail clamp in accordance with the invention in the mounted state. The rail clamp according to the invention com¬ prises two C-shaped parts 1 and 2 interconnected by a tie loop 3. The end portions of the C's are each split up into fingers 4,5, and 6,7. The tie loop 3 comprises a lock-like portion 8, into which fingers 5 and 6 of the C's can be inserted. Thus the end portions concerned are blocked in t event of upwardly directed displacements which might give rise to transgression of the resilience.

The fingers 5 and 6 are slightly longer than the fingers 4 and 7.
