A system for screwless fastening of a rail for a rail vehicle on a foundation comprising - a spring element and - a supporting collar, wherein - the spring element - is bent from a spring wire and - starting from its one end successively has - a bearing section, - a first curved section, connected to the bearing section, - a holding-down section, connected to the first curved section and aligned in the opposite direction to the bearing section, wherein the holding-down section is intended, when in use, to rest on an upper surface of a foot of the rail to be fastened, and - has a second curved section, connected to the holding-down section and curved in the direction of the bearing section and wherein - the supporting collar has - a fastening section, via which the supporting collar is secured to the foundation when the system is fully assembled, - a carrier section supported by the fastening section, and - a bearing recess formed on the carrier section, in which, when the system is fully assembled, the bearing section of the spring element is pivot-mounted about a pivot axis, characterised - in that the spring element has a locking section which is connected to the second curved section and transversely oriented relative to the bearing section, wherein, at least when the spring element is unassembled, there is a distance (a) between the holding-down section and the locking section when seen in a side view, and - in that the supporting collar has a locking head supported by the carrier section, on which an abutment for the locking section of the spring element is formed, such that when the system is fully assembled the locking section is held in a position relative to the bearing section of the spring element, in which the spring element is clamped resiliently elastically between the bearing recess and the abutment of the supporting collar and the holding-down section resiliently elastically acts on its associated surface of the rail foot. -
