Abstract
A connecting structure, which is located between a first object and a second object, includes a first engaging member and a second engaging member located between the first engaging member and the first object. The first engaging member is located between the second engaging member and the second object. The second engaging member has a thickness. When a distance between the first engaging member and the first object is less than or equal to said thickness, the first engaging member and the second engaging member are not movable relative to each other. When said distance is greater than said thickness, the first engaging member and the second engaging member can be moved in a direction relative to each other, moving the first object and the second object relative to each other as well. A covering device for an opening of a building is also disclosed, which includes said connecting structure.
