Retaining assembly for a trim element of a vehicle

An assembly for retaining a trim element to a bodywork element of a vehicle between which an airbag is intended to be interposed, the assembly comprising:

• the trim element, and
• a clip-holder made integrally in one piece with the trim element, comprising:
• a proximal portion connected to the trim element, and
• a distal portion on which is mounted a clip shaped for fastening to the bodywork element,
• the proximal portion and the distal portion being secured via a frangible region configured to break up upon deployment of the airbag, and
• the distal portion being displaceable between a rest position in which the frangible region secures the distal portion and the proximal portion and a deployment position in which the distal portion is disengaged from the proximal portion by breakage of the frangible region, and
• a retaining element configured to retain the distal portion to the trim element when the distal portion is in the deployment position, wherein the distal portion comprises a mounting wall provided with a mounting orifice, configured to cooperate with a complementary mounting member provided on the clip for mounting the clip on the distal portion.
