M58-10-B 90 PCT Abstract of the Disclosure. An antifriction insert for switching devices and also for slide surfaces for movable frog points, and a method of securing such an antifriction insert to the slide base of switching devices. The antifriction insert (1) for slide surfaces of switching devices is fixed to a base member (5) in that the base member includes a recess with grooves at both sides. At least one of the grooves has upwardly open hollows (9). The antifriction insert has projections associated with these hollows (9) so that the antifriction insert can be introduced from above into the base member (5) and then only needs to be displaced by the length of the projections in order to obtain safe securing.
