摘要： PURPOSE: To joint a tube rapidly which has outside conical plug-in end with male thread at one end and an inner conical plug-in socket with female thread at other opposite end by pressing the outside conical plug-in end into the plug-in socket and making them screw-locked. CONSTITUTION: For example, a conical plug-in end 3 is formed at one end of tube 2 which is one of pre-press tube 1, 2 made of thermal plastic resins such as polyethylene. An inner conical plug-in socket 4 into which the end 3 of tube 2 may be pressed in is formed at end of the other tube 1. Male thread 7 and female thread 8 are formed respectively in outside conic division 5 of the plug-in end 3 and inner conoid 6 of the plug-in socket 4. These male thread 7 and female thread 8 are engaged to form a shape locking as well as a force locking. As a result, while two tubes are simply and rapidly connected, the most suitable tightness with a smooth tube surface is achieved.
