An apparatus for ending a tubular pile foundation includes a substantially plate-shaped pressure distribution plate which comprises a substantially flat plate surface and a contact surface opposite the plate surface for a structure to be erected on the tubular pile foundation. The pressure distribution plate can be fitted with the plate surface onto a pile end of a tubular pile of the tubular pile foundation. At least one centering collar for centering the apparatus on the pile end is arranged on the plate surface, and at least one support structure for reinforcing the pressure distribution plate is arranged on the contact surface.
