Manfrotto 190xdb Tripod Manual Are Quick Release Tripod Legs Replacable?

Are quick release tripod legs replacable? - manfrotto 190xdb tripod manual

I have a Manfrotto tripod quick 190XDB has no legs. I wonder if my possile current version, buy a screw to replace fast - or I should have a new tripod that has this feature if you want a quick exit? If so, where can I do?
Thanks
