Abstract: A retention clip for securing a trim piece to a vehicle. The retention clip includes a trim piece affixing portion, a first leg member, and second leg member that extends from a head portion. The trim piece affixing portion is defined by at least one pair of grips that includes a plurality of retention barbs. Each first and second leg member is defined by a first leg portion, an intermediate knee portion, and a second leg portion. Each second leg portion is defined by a first and second length and a first and second deployment angle, respectively. The retention clip has a resilient retention feature that allows the retention clip to deform inwardly to during installation, then outwardly when affixing a trim piece to a vehicle in order to provide a perpendicular biasing force and a later, outboard biasing force.
