  • a covering 103 and a covering film 104 are arranged between the substrate 102 and the component 101 .
  • the fastening device 100 comprises a fastening element 110 and a nail 120.
  • the fastening element 110 has a plate 111 for holding the component 101 against the base 102, a hollow shank 112 protruding from the plate 111 with a shank base 113 and one of the shank base
  • the shaft bottom 113 has a passage
  • the sleeve 115 preferably the entire fastening element 110, consists essentially of a thermoplastic material.
  • the nail 120 comprises a nail shank 121 with a nail tip 122 , which is in particular conical, and a nail head 123 with a head diameter which protrudes beyond the nail shank 121 .
  • the nail 120 is positioned in the passage 114 such that the sleeve 115 abuts the nail shank 121 and surrounds the nail shank 121 .
  • a diameter of the nail head 123 is larger than an outer diameter of the sleeve 115.
  • the nail 120 consists essentially of steel.
  • FIGS. 2 and 3 A section of the fastening device 100 during fastening to the subsurface is shown in FIGS. 2 and 3 .
