The assembly also comprises a multi-piece connector comprising an inner ring, a fitting and an outer ring. The inner ring has an outer diameter greater than the inner diameter of the feeding tube and is coaxially disposed within the feeding tube by a friction-fit. The fitting comprises a front portion, an intermediate portion and a rear portion, the intermediate portion including a shoulder having an outer diameter greater than the inner diameter of the feeding tube. The front portion of the fitting is inserted through the rear end of the dilator and is secured to the dilator by a plurality of barbs.
