| 摘要 |
The invention relates to a flange device which can be secured to two tubular elements (41), characterised in that a first (3; 31) and a second (5; 33) flange element are provided with an orifice (13, 13') and a substantially semi-circular open-edged recess (9, 9'); in that said orifice (13, 13') comprises a first substantially semi-circular (15a, 15a') section and a second substantially semi-circular (15c, 15c') section, wherein the radius of the first section (15a, 15a') is smaller than the radius of the second section (15c, 15c'); and in that both flange elements (3, 5; 31, 33) can be joined to each other in such a way that the respective recess (9, 9') of one flange element (3, 5; 31, 33) forms a substantially circular opening with the first section (15a, 15a') of the orifice (13) of the other flange element (5, 3; 33, 31) in order to receive a tubular element (41). |
