An anchoring device including an anchoring element suitable for being anchored an object of construction material with the aid of mechanical vibrations. The anchoring element includes a thermoplastic material and a tool. The thermoplastic material forms at least a part of a radially outer surface of the anchoring element, and the tool has a proximal portion and a broadening portion distally of the proximal portion. The broadening portion has an outer second cross-section, the second cross section being larger than the first cross section but being adapted to the first cross section so that the tool can be moved with respect to the anchoring element while the broadening portion is in the axially-extending opening and locally expands the anchoring element while thermoplastic material of the anchoring element that surrounds the broadening portion is in a solid state.

1. An anchoring device, comprising: an anchoring element suitable for being anchored in an object of construction material with the aid of mechanical vibrations, wherein: the anchoring element extends along an axis,the anchoring element comprises a thermoplastic material that forms at least a part of a radially outer surface of the anchoring element, and,the anchoring element has an axially-extending opening, the axially-extending opening having a first cross section,the anchoring device further comprising a tool with a proximal portion and broadening portion distal of the proximal portion, wherein: the broadening portion has an outer second cross-section, the second cross section being larger than the first cross section but being adapted to the first cross section so that the tool can be moved with respect to the anchoring element while the broadening portion is in the axially-extending opening and locally expands the anchoring element while thermoplastic material of the anchoring element that surrounds the broadening portion is in a solid state,the proximal portion of the tool being equipped for being coupled to a vibration source,whereby the anchoring element is capable of being anchored in the object by mechanical vibrations coupled into the tool while the tool is moved relative to the anchoring element, and, by the effect of the broadening portion expanding the anchoring element, a radially-outer surface of the anchoring element is pressed against a wall of a bore of the object, whereby by the common impact of the vibrations and the expansion at least a part of the thermoplastic material of the anchoring element is liquefied and pressed into structures of the object to form, after re-solidification, a form-fit connection with the object. 2. The anchoring device according to claim 1, wherein the axially-extending opening is open towards a proximal end of the anchoring element, whereby the tool is capable of being at least one of: inserted from the proximal side for anchoring the anchoring device and retracted after the anchoring process. 3. The anchoring device according to claim 2, wherein the axially-extending opening is a through opening extending through the anchoring element from a proximal end to a distal end thereof. 4. The anchoring device according to claim 3, wherein at least one cross-section of the proximal portion of the tool is smaller than the first cross section. 5. The anchoring device according to claim 1, wherein a proximal portion of the tool comprises a retaining structure and is shaped to be anchored by the anchoring element. 6. The anchoring device according to claim 5, wherein the proximal portion of the tool comprises a thread. 7. The anchoring device according to claim 1, wherein a distal portion of the tool, which distal portion forms the broadening portion, is equipped with retaining structures that cause the tool to be retained by the anchoring element. 8. The anchoring device according to claim 1, further comprising a counter element shaped to be held against a proximal end of the anchoring element while the tool is pulled while the broadening portion is within the axially-extending opening. 9. The anchoring device according to claim 1, wherein the broadening portion is a distal end portion that is able to be moved in the anchoring element in the axial direction thereby expanding the anchoring element locally. 10. The anchoring device according to claim 1, wherein the anchoring element is cup-shaped. 11. The device according to claim 1, wherein the proximal tool portion is a tool shaft. 12. The anchoring device according to claim 11, wherein the tool shaft comprises a thread. 13. The anchoring device according to claim 1, wherein the proximal tool portion is a cable element. 14. The anchoring device according to claim 1, wherein the broadening portion is adapted to the first cross section so that the tool is capable of being moved axially within the axially-extending opening, thereby expanding the anchoring element locally. 15. An anchoring assembly, comprising the device according to claim 1 and further comprising a source of mechanical vibration equipped for being coupled to the proximal portion of the tool.
