Simply connected, because it has no holes in it! If you take two arbitrary paths from a point $\displaystyle a$ to different point $\displaystyle b$ then you can find a set of paths that fills in the gap - you can drag one path into the position of the other path. There is nothing there to stop you - there are no holes!
