摘要： Two plastic tubelike members on which an annular protrusion or an annular groove are respectively provided to be used as two constructive block members for assembling valve or joint devices are directly coupled to assemble such devices. Critical dimensional relationships on the coupling end having the annular groove are established wherein a deformation process can be controlled to engage the annular groove with the annular protrusion by a radially widening motion and an axially spring motion in elastic dynamics, while the coupling end having the annular groove is softened by heating to become elastic. High coupling accuracy can be secured with high coupling strength and durability.
