Have you looked at your anchor clip lately? Does it have one of these little plastic pieces sitting on it? If it doesn’t, you need it! It is a requirement of the safety standards to have what’s called an attachment clip (here is an AB type) to reduce the chances of your anchor clip coming loose, especially if you fit it upside down. Sooo if you don’t have one, contact your manufacturer or authorised fitting station to get one - they should be under $5.
