Abstract
A system for a screwless rail fastening includes a spring element and a supporting collar. The spring element has a bearing section, a curved section, a holding-down section, aligned in the opposite direction to the bearing section, a curved section curved in the direction of the bearing section, and a locking section aligned transversally to the bearing section. The supporting collar includes a fastening section for retaining the supporting collar on the foundation, a carrier section supported by the fastening section, a bearing recess formed on the carrier section for mounting of the bearing section, and a locking head supported by the carrier section on which a counter-bearing for the locking section is formed so that the locking section is retained in a position relative to the bearing section of the spring element.
