You don't need to hide it.
That link is not displaying anything. I'm getting the error:
Not Found
The requested URL /mohairbearmakingsupplies.co.uk/ was not found on this server.
Normally, before you activate the SSL redirection on HikaShop, that URL has to display your website.
Since that is not the case, it's normal that it doesn't work.
Having that URL display your website is something which should be setup by your hosting company normally. As I feared, it seems that your hosting company does not configure the shared SSL URL so that it automatically displays your website.
Unfortunately, we can't do anything on that and as eliot said, you'll need to see that with your hosting company.
Once you have your website displaying when you go to
web110.secure-secure.co.uk/mohairbearmakingsupplies.co.uk/
then you can simply enter that URL in the shared SSL option of HikaShop and it should work.
