Abstract
A plastic coupling for plastic tubing having a groove annulus formed between a first circumferential groove on the outer periphery of the enlarged diameter portion of a connection tube and a second circumferential groove on the inner periphery of a cap nut 5 when the cap nut 5 is mounted on a joint body, and an enlargeable split ring having an internal diameter smaller than the external diameter of the enlarged diameter portion and loosely fitted into the second groove, the split ring being adapted to slide on the enlarged diameter portion to the first groove until the split ring falls within the first groove and is located within the groove annulus when the cap nut is mounted on the joint body.
