A system comprises a hinge assembly and an anchor. The anchor has a base, a head, and a pin connecting the base and the head. The hinge assembly has an aperture and a notch narrower than the aperture extending from the aperture. The head fits through the aperture, and the notch is configured to receive the pin when the hinge assembly is translated toward the pin with the head through the aperture. The hinge assembly releasably clips to the pin to retain the hinge assembly in an engaged position when the notch receives the pin. The system may be a cargo system in a vehicle, with the lid serving as a vehicle load floor. A method of securing a lid to a cargo bin in a vehicle utilizes the system.
