A B S T R A C T Toggle (10) which can be set form-fittingly on the undercut surface of a bore provided with an undercut, having an elongated fastening bolt (18) on whose bore-internal end locking elements (22) are mounted, which can be rocked outwardly by a conical component (28) disposed axially displaceably on the fastening bolt (18) from a position lying within the diameter of the bore (12) to a position engaging the undercut surface (17). The locking elements (22) are supported on a bottom piece (20) on the bore-internal end of the fastening bolt (18) and have the form of sleeve segments integrating, in the non-outspread position, a thick-walled sleeve. Between the axially displaceably disposed conical com- ponent (28) and a bolt head provided on the outer end of the fastening bolt, or a nut (38) screwed onto a thread at this same end, there is disposed a coil spring (32) which can be palced under bias by axial compression. The locking elements (22) can be fixed against rocking to the locking position, in which case means are provided for the release of this fixation after at least the partial introduction of the toggle (10) into the undercut bore (12).
