Quite right - it isn't.
Or at least it is only attached by muscles and ligaments. This is true
of almost all tetrapods. (Birds are about the only exception I know of).
This is why the reconstruction of the shoulder region is so contentious
- there is no bone-bone articulation to use to position the shoulder.
Go take a look at those mounted ceratopsians, you will see that the
shoulder is attached by an iron bar.
The peace of God be with you.
