ABSTRACT:
A plastic quick-connect connector for connecting a plastic tube or fluid line to a connector stem. A elastically expandable plastic compression sleeve is slid over the end of the mating plastic tube or fluid line. The connector stem receives the plastic tube and surrounding compression sleeve the stem to expand the plastic tube and the tightly surrounding compression sleeve radially outwardly into a gripping relationship with the stem therebetween. The compression sleeve is of a material which does not relax at elevated temperatures on the order of 350.degree. F. This arrangement prevents creep or relaxation of the plastic tube or fluid line which, in turn, prevents an undesired pull-off, or separation of the completed connection.
