A method suitable for anchoring an anchoring element in an object, which anchoring element is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral anchoring element surface and the compression axis. The anchoring element has a coupling-in face which serves for coupling the mechanical vibrations into the anchoring element, which coupling-in face is not parallel to the compression axis. The anchoring element further includes a thermoplastic material which in areas of the peripheral surface enlargement forms at least a part of the surface of the anchoring element, the method includes the steps of: providing a bore in the object; positioning the anchoring element in the bore; and coupling the compressing force and the mechanical vibrations through the coupling-in face into the positioned anchoring element.

1. An anchoring element suitable for being anchored with the aid of mechanical vibrations in a bore in an object, the anchoring element comprising: a coupling-in face, anda thermoplastic material forming at least a part of an anchoring element surface,the anchoring element being capable of being compressed along a compression axis not parallel to the coupling-in face when a compressing force is applied to the coupling-in face;wherein at least one of the following conditions is fulfilled: the anchoring element comprises at least two components, which are designed to be shifted relative to each other by the compressing force along shifting surfaces extending obliquely to the compression axis;the anchoring element is one piece and is spreadable;the anchoring element is one piece and comprises buckling locations, in which the anchoring element buckles through the effect of the compressing force;whereby the anchoring element is shaped to be expanded so that a distance between a peripheral anchoring surface of the anchoring element and the compression axis is locally enlarged when a compressing force is coupled into the anchoring element via the coupling-in face while the thermoplastic material is in a solid state;wherein the thermoplastic material forming at least a part of the peripheral surface of the anchoring element is arranged at least in regions of the peripheral anchoring surface;wherein the anchoring element is further capable of transmitting mechanical vibrations from the coupling-in face to the anchoring surface;so that, when the anchoring element is positioned in the bore and a compression force and mechanical vibrations are coupled into the anchoring element via the coupling-in face, the anchoring element is caused to be compressed and, due to the distance enlargement, to be pressed at least locally against the side walls of the opening and therewith the thermoplastic material is allowed to be at least partly liquefied where it is in contact with the side walls and to be pressed into structures of the object in order to form a form-fit connection after resolidification. 2. The anchoring element according to claim 1, wherein the coupling-in face is at least partly even and oriented perpendicular to the compression axis. 3. The anchoring element according to claim 1, wherein the anchoring element comprises at least two components, which are designed to be shifted relative to each other by the compressing force along shifting surfaces extending obliquely to the compression axis wherein at least one of the components is spreadable by the compressing force. 4. The anchoring element according to claim 1, wherein the anchoring element comprises at least two components, which are designed to be shifted relative to each other by the compressing force along shifting surfaces extending obliquely to the compression axis, wherein the components of the anchoring element, prior to anchoring, are separate or linked via predetermined breaking or melting points. 5. The anchoring element according to claim 1, wherein the anchoring element comprises at least two components, which are designed to be shifted relative to each other by the compressing force along shifting surfaces extending obliquely to the compression axis wherein the shifting surfaces are conical. 6. The anchoring element according to claim 1, wherein the anchoring element comprises at least two components, which are designed to be shifted relative to each other by the compressing force along shifting surfaces extending obliquely to the compression axis wherein the surface of the components consist of thermoplastic material at least to the extent that the components are able to be welded together by the effect of the mechanical vibrations and the compressing force. 7. The anchoring element according to claim 1, wherein the anchoring element is one piece and comprises buckling locations, in which the anchoring element buckles through the effect of the compressing force, wherein the buckling locations are weak points, which are able to be softened or liquefied by the effect of the mechanical vibrations.
