The assembly also contains a secure part which includes a base and a tongue section extending from the base. The tongue section has parallel guide arms extending from a rear wall and terminating in leading ends. A member secured to the guide arms is configured with reference to the slot to remove debris from the slot through the opening in the cover. A cam surface formed in the tongue section terminates in a catch surface, such that when the secure part is received in the keeper, the cam surfaces engage and the cover deflects upwardly.
