Abstract
Viene prevista una struttura di connettore per unire in modo sicuro una tubazione concentrica per carburare avente una pluralità di tubi ad un collettore avente passaggi per fluido corrispondenti in comunicazione con una pluralità di tubi. Il collettore comprende raccordi d'accoppiamento aventi fori assiali per ricevere un'estremità di ognuna della pluralità di tubi. La struttura di connettore comprende fori di montaggio estendentisi trasversalmente ai fori assiali. Ognuno dei fori di montaggio riceve una vite in modo che il bordo esterno della vite sia tangenzialmente allineato con una circonferenza corrispondente della parete esterna della pluralità di tubi per fissare meccanicamente e sicuramente le loro estremità nei rispettivi fori.
