A fastening device includes a housing and first and second buttons disposed at opposite ends of the housing in a first axial direction. Each of the first and second buttons is actuatable in the first axial direction. The fastening device further includes first and second claws slidably disposed within the housing, each of the first and second claws including a hook portion extending outward from an engagement face of the housing. Each of the first and second claws engages one of the first or second push buttons within the housing so that relative movement of the first and second buttons toward one another moves the hook portions of the first and second claws away from one another in the first axial direction.
