The screw has a head and a shank. The shank is movable along the slot. The nut is threadedly engaged with the shank, and is wider than the first end portion and narrower than the second end portion. The restricting tab can be detachably sandwiched between the nut and the main body such that the shank can be trapped in the first end portion.
