Toggle which can be set against the face of an undercut provided within a bore, and having an elongated bolt, on whose bore-internal end locking elements are mounted, which, by means of a conical component disposed for axial displacement on the bolt, can be expanded outwardly from a position in which they are within the diameter of the bore to a position in which they engage the face of the undercut. The locking elements are supported on a bottom piece on the end of the bolt within the bore, and are in the form of segments of a thick-walled cylinder when in the retracted position. A variety of anti-rotational means are provided to prevent the toggle from turning during the setting operations.
