PROBLEM TO BE SOLVED: To facilitate insertion of a tube by blocking the expansion of a seal member during insertion and to suitably use this pipe coupling in environment demanded of cleanliness by preventing the occurrence of dusting by a sealing member. SOLUTION: This pipe coupling is provided with a pipe body connection mechanism 20 for mounting and demounting a tube, a coupling body 14 having a first passage 12 formed at an interval part and communicating with the tube, and a coupling member 18 integrally coupled to the coupling body 14 and having a second passage 16 communicating with the first passage 12. The pipe connecting mechanism 20 comprises a packing 26 to effect seal function by surrounding the outer peripheral surface of a tube to be inserted, and a stopper member 28 to block slide of the packing 26 by fixing the packing 26. |
