1. A functional part having integrated therein at least one connector for being bonded to an item, the functional part being a car component or a part of a car body, wherein:
the at least one connector extends between a proximal end and a distal end and comprises a connector body forming a proximal surface and a distal surface,
the at least one connector comprises thermoplastic material in a solid state,
the at least one connector comprises a plurality of protrusions that protrude from the distal surface and being spaced from one another, and
the protrusions comprise the thermoplastic material at outer surfaces, wherein the at least one connector comprises a structure designed and arranged to promote local compression of the item when forced into the item,
wherein the structure is provided by a shape of barbs arranged at the distal end of the protrusions, wherein the barbs each comprise at least two pointed ends with a V-shaped, a U-shaped or a W-shaped indentation therebetween,
such that the functional part is adapted to be bonded to the item at bonding locations comprising bonding points that are separate from each other.
