Abstract
The invention relates to a system for securing a rail, including a guide plate for providing lateral support for the rail to be secured, a spring element supported on the guide plate and having at least one spring arm exerting an elastic retaining force on the base of the rail, and tensioning means for tensioning the spring element. Such a system allows an optimally secure support of the rail even in the case of a level ground having no indentations or stop shoulders, whilst being easy to handle and having only a small number of components to be mounted in each case, by providing a support angle which may be connected to the solid ground and which has a bearing surface against which the guide plate rests on the side facing away from the rail base. According to the invention the support angles are made from a plastic material, in order to facilitate assembly and improve the function of the support angles in practical use.
