ABSTRACT OF THE DISCLOSURE A form-fitting connecting arrangement comprises an article having a cylindrical blind bore and undercut surface extending essentially radially outwardly from the blind bore and at a certain distance from the orifice of the bore, and a toggle having an elongated bolt and a toggle body correspond- ing substantially to the diameter of the bore and introducible into the bore. Locking elements are mounted on the toggle body and have ends facing the bore orifice, and are adapted to be swung from a position lying within the diameter of the bore into a position in which they project at least partially beyond the diameter of the toggle body and engage lockingly the undercut surface of the bore. The toggle body is a bottom piece of the bolt, of relatively low height and disposed at the bore-internal blind end of the bolt. The locking elements have bore-internal ends closing together on the bottom piece to form a thick-walled cylindrical sleeve enveloping the bolt, the bolt having a component tapering conically towards the interior of the bore and engaging between the ends of the locking elements facing the bore orifice, so that, upon a displacement of the bottom piece in the direction of the bore orifice, the rearward ends of the locking elements are swung positively radially outwardly; said bolt has on its outer end remote from said blind end of said bore a screw head, or a thread and a nut threaded on the thread.
