Abstract: A clip comprising a connecting base including a bolt introduction hole that is configured such that a bolt member formed on an object member is introduced thereinto. The connecting base includes flexible engagement strips formed on an inner surface thereof and having pressing blocks. The pressing blocks respectively include engagement claws formed on proximal end portions of inner surfaces thereof. The engagement claws engage the predetermined portions of thread groove of the bolt member, so that the connecting base is connected to the object member. In a connected condition of the connecting base, when the engagement claws are disengaged from the predetermined portions of the thread groove due to an extraction force, edge portions formed on distal end portions of the inner surfaces of the pressing blocks engage different portions of the thread groove of the bolt member.
