  • the at least one clip comprises a ring with a face provided with sealing material contacting the body part around the respective hole and an opposite face provided with adhesive adhering to the trim.
  • the opposite face of the ring of the at least one clip comprises a foam layer.
  • the at least one male portion is integrally formed with the trim.
  • the at least one male portion extends from a disk fixed to internal wall of the trim.
  • the at least one clip comprises a hollow protruding portion inserted into the respective hole of the body part, said hollow protruding portion receiving the male portion.
  • the hollow protruding portion comprises at least two flexible wings with end surfaces that engage with the body part around the respective hole.
  • the at least one male portion protruding from the trim comprises at least two engagement surfaces with a distal end of the hollow protruding portion of the at least one clip
  • the trim comprises surfaces around the at least one male portion, in contact with the body part and adhered to said body part.
  • the invention is also directed to a trim for a body part of a vehicle, comprising a trim body and at least one fastener for engaging with at least one hole of the body part, characterized in that the fastener comprises a male portion protruding from a body of the trim and a clip to be inserted in the hole of the body part and for receiving said male portion.
  • the trim corresponds to the trim of the above vehicle.
  • the features of the vehicle relating to the trim apply also to the trim as such.
  • the invention is interesting in that it provides a trim fixation device easier to use than a classical fixation clip and moreover adaptable without modification to all design of trim or/and of body part of a vehicle.
  • the trim fixation of the invention requires less space and is particularly suitable for trims of a reduced thickness and more particularly to be placed on a portion of a body part that is close to form an undercut in a stamping production process.
  • This invention is also particularly interesting in that it decreases the mounting time of a trim by avoiding performing unnecessary undercut in the body part around the insertion hole of the clip.
  • Figure 1a is a view of a trim fixed on a body part of a vehicle with a fastener according to the invention.
  • Figure 1b shows a view of the trim fixed on the body part of the vehicle represented in the figure 1a but under another positioning.
  • Figure 2 is a perspective view of the clip of the fastener according to the invention.
  • Figure 1a depicts a body part 3 of a vehicle on which is attached an exterior trim 5.
  • a fastener 7 which cooperates with the trim 5 and respectively with a hole 9 made beforehand in the body part 3.
  • the fastener 7 comprises two elements, a male portion 11 and a clip 13.
  • the male portion 11 protrudes from the trim 5 while the clip 13 is inserted in the hole 9 of the body part 3 and is precisely configured to receive the male portion 11.
  • the clip 13 actually comprises a ring 15 and a hollow protruding portion 29.
  • the ring 15 presents two faces, the first face 17 is provided with sealing material 19 which contacts the body part 3 around the respective hole 9, and the second face, or opposite face 21, is provided with an adhesive (not visible) adhering to the trim 5.
