The tube connecting apparatus of the present invention is arranged as to hold tubes (7,8) in a first tube holder (1) and a second tube holder (2), to rotate a pair of rotatable clamping members (31,32) which include separable pieces disposed in rotational symmetry for holding the tubes (7,8) in either or both of the first tube holder (1) and the second tube holder (2), to heat and melt the tubes (7,8) by a heated cutting plate (6) moving therebetween to cut the tubes, and to weld cut end faces of the different tubes (7,8). When the pair of clamping members (31,32) are in a state of not holding the tubes (7,8), rotation preventing members (65,66,67/71,72) fixedly locking the clamping members (31,32) in a predetermined position, preventing the clamping member (31,32) from being rotated. |
