  • Plastic coupling with ring for adhesion to a tubular member
    Patent number: 5152557
    Abstract: A coupling for joining two tubes is manufactured of a material different from the material of the tubes. The coupling includes two parts, which can be coupled to each other. Each part includes a body with an axial bore for receiving an end of the tube. The bore has an inner wall including a ring. The ring is made of a material which can adhere to the material of the tube. Two tubes made of different material can thus be coupled and uncoupled.
