The system comprises a spring element, with at least one spring arm, which can be clamped against the foundation by means of a clamping element, an adapter piece, with a contact surface section, which sits on an end section of the spring arm, and a guide plate. The guide plate has a contact surface for the rail foot and a sliding surface which adjoins the contact surface via which the adapter piece can be moved from a pre-assembly position in which it sits on the guide plate with its contact surface section to an assembly position in which it is seated, with its contact surface section, on the rail foot of the rail to be fixed. A stop is provided on the sliding surface against which the adapter piece rests in the pre-assembly position. ## Claims ### Claim 1 A system for fixing a rail onto a foundation, comprising: a spring element which can be clamped against the foundation by means of a clamping element, wherein the spring element has at least one spring arm; an adapter piece which sits on an end section of the spring arm of the spring element, the adapter piece having a contact surface section formed at its periphery; and a guide plate, comprising a face allocated to a rail foot and a free top face; the face allocated to the rail foot having a contact surface, and the free top face having a sliding surface adjoining the contact surface via which the adapter piece can be moved from a pre-assembly position in which it sits on the guide plate with its contact surface section into an assembly position in which it sits, with its contact surface section, on the rail foot of the rail to be fixed, in order to transfer the elastic retaining force exerted by the spring element onto the rail foot, wherein the sliding surface of the guide plate rises in the direction of the contact surface and a stop is provided on the sliding surface against which the adapter piece rests in the pre-assembly position. ### Claim 2 (depends on 1) The system according to claim 1, wherein the spring element is an ω-shaped clamp with two spring arms, such that one adapter piece is allocated to each of the spring arms, and such that on the guide plate a sliding surface which rises in the direction of the contact surface is provided for each of the adapter pieces. ### Claim 3 (depends on 1) The system according to claim 1, wherein the adapter piece electrically isolates the spring element from the rail foot. ### Claim 4 (depends on 1) The system according to claim 1, wherein the adapter piece is mounted on the end section of the spring arm to be rotatable on a rotary axis, such that the adapter piece has at its periphery at least two contact surface sections, one of which in each case, depending on the rotary position of the adapter piece at the time, rests against the rail foot, and such that one contact surface section of the adapter piece has a greater distance from the rotary axis of the adapter piece than the other contact surface section. ### Claim 5 (depends on 1) The system according to claim 1, wherein a support plate is provided which extends transverse to a rail to be fixed over the width of the guide plate and which wherein the support plate is arranged to compensate for height differences between the guide plate and a foundation, the support plate having a rectangular base form and having a passage opening for a clamping element used for clamping the spring element, and wherein the support plate being is divided into two parts along a joint line which, starting from a long side of the support plate aligned transverse to the rail to be fixed, is guided at a distance from a short side to a passage opening and from there, intersecting the passage opening, is guided in the direction of the short side of the support plate. ### Claim 6 (depends on 1) A guide plate for a system formed in accordance with claim 1, the guide plate having a contact surface on its face allocated to the rail foot and on its free top face a sliding surface, for an adapter piece, which adjoins the contact surface, wherein the sliding surface of the guide plate rises in the direction of the contact surface and a stop is provided on the sliding surface by which a pre-assembly position for the adapter piece is defined. ### Claim 7 (depends on 6) The guide plate according to claim 6, wherein the sliding surface is even and of a uniform inclination. ### Claim 8 (depends on 6) The guide plate according to claim 6, wherein the stop for the adapter piece which is present on the guide plate is in the form of a step integrally formed on the guide plate. ### Claim 9 (depends on 6) The guide plate according to claim 6, wherein there is formed on its contact surface a protrusion which protrudes towards the rail and which is provided for engaging below the rail foot in the assembly position. ### Claim 10 (depends on 6) The guide plate according to claim 6, wherein a recess is formed in its underside. ### Claim 11 (depends on 6) The guide plate according to claim 6, comprising a support section on its side facing away from the contact surface, which has on its top face a contact surface to support a transition section of the respective spring element in a pre-assembly position and which at the same time limits a channel formed in the guide plate in which the transition section of the spring element sits in the fully assembled position. ### Claim 12 (depends on 11) The guide plate according to claim 11, wherein at least one recess is formed in the support section from the side facing away from the contact surface.
