This question doesn't really make sense... The clavicle is the collarbone. The sternum - usually people are referring to the manubrium when talking about the sternum - is the hard bone that looks like the body of a necktie protecting your heart in the front of the body. The ribs attach to the sternum in front, to the spine in back. The clavicle attaches to the sternum at the notch at the base of your neck. When you protract the shoulders (hunch them forward), the notch is more pronounced for ease of location. In fact, the sternoclavicular joint is the only skeletal attachment of the shoulder complex. So really, the clavicle doesn't join the sternum to anything. The clavicle is joined to the sternum, giving the shoulder girdle it's one attachment to the axial skeleton.
