The system for mounting objects on walls comprises a bolt and a wall plug (2). This has a central bore (3), into which the bolt is screwed, and is made up of two sections (4, 5) separated by axial expansion slits. These are bridged by connector strips (7) which are as long as or longer than the width of the slits.
