Remove Register Link

I do not want people to be able to register themselves. So Registration is not allowed within my wordpress settings. I need to remove the Register link on the plugin login page but I can’t see a way to do this. So I end up with the standard wordpress login page with an error message saying registration is not allowed. The best I seem to be able to do is change the registration page to the login page in the settings so the link just represents the new login page. Editing the form does not provide a way of removing this link. Can I get rid of this link?

The page I need help with: [log in to see the link]
