class RegisteredUser(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    email = models.EmailField(unique=True)
    password = models.CharField(max_length=10)
    connected_users = models.ManyToManyField('self', blank=True, symmetrical=False)

    def __unicode__(self):
        return self.email

the api now looks like this:

ru = RegisteredUser.objects.get(id=1)
another_user = RegisteredUser.objects.get(email='name@example.com')
ru.connected_users.add(another_user)
uc = ru.connected_users.all()
for user in uc:
    print user.first_name, user.last_name, user.email
