  "textContent": "A fastening system comprising an elongated profiled rail (3) fastened to a fixed base (2) and having a groove (4) with two opposite side walls (6, 7); and locking element (9) connected to a mount (7) and fitted to the groove (4) of the profiled rail (3). The locking element (9) comprises stop faces (10, 11) which can be pressed against the side walls (6, 7) of the groove (4) to produce frictional engagement. The side walls (6, 7) of the groove (4) comprise first wedge surfaces (12, 13), which are mutually disposed at an angle ( alpha ) opening towards the fixed base (2). The stop faces (10, 11) of the locking element (9) constitute second wedge surfaces (14, 15) mutually disposed at a corresponding angle. The frictional engagement produced by the wedge surfaces grows stronger as the load increases, due to the wedging effect. The fastening system comprises a supporting element (16) fastened to the mount and fitted to be supported on the profiled rail (3). A spring (17) has been arranged to act between the mount (8) and the locking element (9) to press the wedge surfaces (12, 13; 14, 15) against each other. Using a releasing device (18), the locking element (9) can be moved against the spring force of the spring (17) from a locked position (I) to a released position (II) to separate the wedge surfaces from each other.",
