You could try a local car breakers. Its no longer necessary to carry dog biscuits to distract the guard dogs

Or there are several 'parts finder' web sites on line. You enter your car details and the part you need, free of charge. . Various car breakers throughout the country monitor the site and if they have a Jazz in the yard they will contact you through the site with an offer of price and carriage. You can often pay through the sites own secure payment system. A bit like a personalised ebay.
Or if you still have the broken part you can do quite a strong repair on some plastics by 'welding' it back on using a soldering iron and melting a cable tie into the joint as a filler/glue. . Or maybe drill a couple of small holes and use a cable tie instead of the clip.
