A trim panel (10) includes at least one integrally-formed first member (12) and at least one integrally-formed second member (14) extend from an outboard surface (16) of the trim panel (10). The at least one integrally-formed first member (12) engages an inboard surface (42) of a barrier (36) to push the barrier (36) in an outboard direction. The at least one integrally-formed second member (14) extends through an opening or perforation (40) of the barrier (36) to retain the barrier (36) to the trim panel (10). The barrier (36) may be a water/acoustic ingression barrier (36). The at least one integrally-formed first member (12) causes an adhesive bead (44) arranged on an outboard surface (46) of the barrier (36) to positively engage an inboard surface (48) of an inner door panel (38). The at least one integrally-formed second member (14) extends through an opening or perforation (40) of the barrier (36) to retain the barrier (36) with the interior door trim panel (10).
