Hello Thomas, I found your car in the article! Mini part sounds right, and a Jubilee / Hose clip can help as LD says. These are the circular metal strips with little slots around them, and a small lump which holds a screw; when you turn the screw with a screwdriver it works in the slots to make the clip bigger or smaller. Yacht Suppliers Shops (Chandlers) sell stainless steel (Inox) Jubilee Clips which are more expensive but look nicer and can be done up tighter than normal ones. You might need two. Do not use cheap ones because they are much less strong than good quality Brands
