Abstract
A tubing/fitting connection provides secure sealing attachment of a tubing to a fitting. In a described embodiment, a flexible tubing is connected to a non-rigid fitting using a retainer which grips both the tubing and the fitting. The retainer also internally supports the tubing, and may sealingly engage both the tubing and the fitting.

A tubing/fitting connection, comprising:
- a flexible tubing;
- a fitting made from a non-rigid material having a portion thereon for receiving the tubing;
