In a switch blade (point-rail) device in a grooved-rail turnout on a tram- or streetcar-type line, switch blades (2) are detachably mounted, using a clamping wedge (5) which is fastened to a support part (6) by means of a screw (12) in an essentially perpendicular direction to the running surface. Once the clamping wedge (5) has been removed, the switch blade (2) can be demounted and lifted out. Mounting is performed by pressing an inclined lateral surface (7) of the switch blade (2) against a correspondingly inclined lateral surface (8) of the support part (6). The angles of inclination of the wedge, and of the contact surface of the support part, are matched to each other so that self-locking is achieved.
