Abstract
There is described an improved apparatus for use in medical applications. The invention is adaptable for either disposable or non-disposable use. The apparatus includes a tubing which has a spiral configuration and a "spin-in cuff" or connector with a spiral end which mates with the spiral tubing to form a connection which is secure, substantially fluid leakproof, and yet readily engageable and disengageable. The cuff (or connector) is adapted to interact with existing medical equipment.
