Abstract
A coupling receives a non-metallic tube ( ) in an opening of a coupling body ( ). A seal assembly ( ) disposed inside the coupling body ( ) seals between the body ( ) and the tube ( ). A collet ( ) disposed in the coupling body ( ) includes a tapered external surface ( ) that engages a tapered wall in the coupling body ( ) to resist pull-out of the tube ( ). The collet ( ) includes an inner toothed ( ) surface for gripping the tube ( ) and has a split ( ) or slots ( ) that allow the collet ( ) to radially expand and contract. A rotation prevention member, which in a preferred embodiment is a longitudinal rib ( ) extending inwardly from the collet ( ), limits relative rotation between the collet ( ) and the tube ( ). Moreover, edges ( ) of the split ( ) are rounded so that the collet can rotate relative to the coupling body ( ).
