In the field of a slide rail for tensioning and guiding an endless drive member, comprising at least one bore and a screw captively held in the bore, permitting the captive mounting of screws even in thin-walled slide rails is provided. A sleeve is mounted in the bore and the sleeve comprises engagement elements at its end facing the rail, said engagement elements being engaged with the wall of the bore, and a stop collar lying against a stop surface formed at the slide rail, and lock elements are embodied in the sleeve which engage the thread of the screw and lock the screw at least in an assembly position, wherein said slide rail is thin-walled. Furthermore, an assembly method is provided for manufacturing the slide rail with a captively held screw and to the loss prevention device per se.
