Method of connecting a press-in bolt with a metal sheet and cover element for carrying out the method

A cover element, comprising:

• a receiving opening and configured for press-fitting upon a shaft portion of a press-in bolt, said receiving opening having an inner circumferential surface with malleable wall sections which extend in an axial direction and are spaced from one another about the inner circumferential surface and which form an inner circle defined by a diameter which is smaller than an outer diameter of the shaft portion of the press-in bolt,
• wherein the press-in bolt is forced in a pilot hole of a metal sheet positioned upon the cover element as the metal sheet is supported by the cover element in its capacity as a die, until a head portion of the press-in bolt rests upon one side of the metal sheet and the cover element is pressed upon a profiled shaft portion of the press-in bolt and radially deformed to rest upon another opposite side of the metal sheet,
• wherein the cover element is formed detachably at an end of the cover element in an area distal to the receiving opening with a sliding sleeve which is defined by an inner diameter in correspondence with an outer diameter of the die in an non-deformed state, and
• wherein the sliding sleeve is moved over the cover element to thereby press the cover element upon the shaft portion.
