Date Oct. 4, 1990.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. |
