A fastener assembly for detachably connecting a molded door trim panel to an apertured inner door panel of a vehicle, where upon disassembly, the fastener assembly will disengage, or a replaceable portion will fracture without damaging the molded door trim panel. A detent is utilized to connect a hook portion to a retainer housing that is molded into the molded door trim panel. Upon the hook portion being mistakenly pulled against the inner door panel during disassembly, the detent will either disengage the hook portion from the retainer housing, or the hook portion will fracture before the retainer housing is damaged or disconnected from the molded door trim panel. By preventing damage to the retainer housing and molded door trim panel, only the hook portion of the hook fastener assembly need be replaced or reconnected, instead of the entire molded door trim panel.
