A fitting assembly for corrugated tubing comprising a body having first connecting means; an insert; locking means having second connecting means; and a resilient ring. The insert is sealingly engaged with the body and includes a transition area of increased outside diameter. The locking means includes an internally directed lip; a substantially conical section; and a retainer disposed between the second connecting means and the conical section. The first and second connecting means engage to removably secure the body to the locking means and to slide the ring within the conical section towards the lip forcing the ring to radially contract into a trough of a corrugated tube and sliding the corrugated tube onto the transition area. Further engagement of the first and second connecting means causes the ring to push on and collapse a ridge of the corrugated tube against the transition area creating a seal therebetween.
