Abstract: An insert and a tailgate cable assembly incorporating the same. The tailgate cable assembly is a cable having eyelet connectors at each end and which is used to secure the sidewall of a vehicle to a rotatable tailgate. Fasteners extending from the sidewall and tailgate are received through apertures in the eyelets. At least one of the eyelets incorporates a removable insert that is rotatable between a first position, where the fastener may be either inserted or withdrawn from the eyelet, and a second position where the insert locks the fastener within the aperture in the eyelet. The insert is a “C”-shaped member that interlocks with the eyelet's interior peripheral surface surrounding a portion of the aperture.
