Abstract: A retention structure includes a retainer housing for retaining an object, such as a fastener, commonly used to secure trim panel to an inner vehicle panel. The retainer housing is defined by a first sidewall, a second sidewall, a back wall, and a base. The first sidewall, the second sidewall and the back wall extend from a substrate to the base. The base includes an insertion slot and a retention portion for retaining the fastener. The retention portion includes at least one cutout for increasing the flexibility of the base. The retainer housing also includes a holding arm integral to the retainer housing. The holding arm acts provides a biasing force on the fastener once the fastener is inserted into the retaining portion and restrains lateral movement of the fastener. This abstract submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
