Abstract
A coupler which is for tubing and which has a tube receiving bore therein. A sealing ring, spacer ring and lock ring are coaxially located within the coupler bore. When a tube is inserted into the coupler bore, the sealing ring makes contact between the coupler and tube with the spacer and locking ring cooperating to cause the locking ring when the tube is pressurized to firmly engage the tube, thus preventing the tube from being withdrawn from the coupler.
