The flexible tube coupling has a tubular element (1) made of a flexible material and a rigid tubular flange element (3), which has a connecting surface (3a). The flexible tubular element and the flange element are arranged together. The connecting surface of the flange element has a recess (3a-1) or a bulge that is designed such that it stays in contact with material of an area (1d) of the tubular element, if the connecting surface and an opposite connecting surface are compressed with the tube line at both sides of the material area during the manufacturing a connection of the tube coupling. |
