Provided is a clip structure which can prevent components from falling off an attaching body or an attached body with a simple structure. Further provided is a holding structure for an internal member of a vehicle which can prevent the components from falling off an exterior member or an interior member with a simple structure. A clip assembly (11) includes a first clip having a clip (34) attached to a bracket (25), and a joint (36) as a removable portion connected to the clip 34; and a pin (38) as a second clip connected to the joint (36) and sandwiching a roof head lining (14) between the pin (38) and the joint (36). A holding load (F5) for releasing connection between the clip (34) and the joint (36) is sufficiently small compared to a holding load (F6) for releasing connection between the joint (36) and the pin (38).
