A plug-type coupling is provided to simplify the operation of opening the coupling and reduce the load of the coupling according as the separation member is made of a plastic material. A plug-type coupling(1) is composed of a connection element(2) mounted with an aperture(4) and a receiving pipe body(5) extended at the aperture; and a connection piece(7) formed with a holding rib(9) projected to the outer side at the circumference to form a locking surface(10), and inserted in the receiving pipe body. The holding rib is formed to interact with a locking loop(15) and the locking loop has at least one leg unit having the horizontal elasticity at the aperture. A separation member(27) is movably mounted in the connection element, and the separation member interacts with the leg units to the opening direction. |
