A trim element having a visible side (12) formed of a skin (10), the element includes a skin (10) laid on a plastic foam (24) bonded to the skin by a continuous bonding layer (26) formed spontaneously at the skin-foam interface during the foaming operation, the skin (10) has a preferential rupture initiator comprising at least one scored feature. Throughout the region in which the scored feature lays, the bonding layer (26) is in contact only with the skin (10) and the foam (24), and, at the scored feature and in the direction of the thickness of the skin, the bonding layer (26) is laid over the opening with a thickness very much smaller than the depth of the scored feature.
