At a crossing, rubber interface strips are positioned between the rails and the asphalt or concrete. A U-shaped spring-clip fits underneath the rail, and has upstanding arms that carry tappets, which engage the strips. One of the arms is threaded, and carries a screwed tappet-rod. Turning the tappet-rod closes the distance between the tappets, clamping the strips onto the sides of the rail, and forcing the springy arms apart. The spring-clips are manipulated into position while in an unstressed condition. The spring-clip is only brought up to force when finally assembled. Assembly can be done without tools, and with little danger of mix-assembly, or of injury to workers.

The buckle device according to claim 7, wherein the frame (10) comprises: a base plate part (11); a pair of opposing side plate parts (12) rising from the base plate part (11); and a pair of long holes (16) formed on the side plate parts (12), characterized in that the lock bar (30) is being passed through the pair of long holes (16) and mounted across the pair of side plate parts (12), and the stop restricting part is comprised of a pair of receiving parts (55) for receiving the both end parts of the lock bar (30) which project outwardly from the pair of side plate parts (12). 9. The buckle device according to claim 7, characterized in that a stopper part (18) for locking the release button (50) against the urging force of the biasing member urging the lock bar (30) is integrally formed on the frame (10). 10. A buckle device comprising a tongue plate (2) to be connected to a webbinq, and a buckle body (5) into and from which the tongue plate (2) is inserted and extracted, said buckle body (5) comprising: a frame (10), wherein the frame (10) comprises: a base plate part (11); a pair of opposing side plate parts (12) rising from the base plate part (11); and a pair of long holes (16) formed on the side plate parts (12); a hook member (20) pivotably mounted on the frame (10), said hook member being adapted to pivot to come into engagement with the tongue plate (2) upon insertion of the tongue plate (2) and being pivotally urged in the disengaging direction all the time; a release button (50) made of plastics and for releasing the engagement between the hook member (20) and the tongue plate (2); and a lock bar (30) adapted to move to a first position in which the lock bar inhibits pivoting of the hook member (20) in the disengaging direction, by an urging force of a biasing member when said hook member is being engaged with the tongue plate (2), and move to a second position, in which the lock bar allows pivoting of the hook member (20) in the disengagement direction, by being pushed by the release button (50) upon disengaging operation of the release button (50); said buckle device being characterized in that a stop r
