Safety pins have coils for two main reasons, one of which is ease of manufacturing. It is much easier to mass produce them if they are made primarily out of one strip of wire. The second reason is that the coil causes tension and makes it tso that the pin is forced into the cover, keeping it "safe" and closed over what it is holding as well.
Of course there is also the theory among many people that it has a coil because it could not come up with any other shape with which to confuse you so therefore decided that a coil form would suffice.
