PROBLEM TO BE SOLVED: To provide a one-touch packing having no trouble in which a pipe is pressed against a seal piece of the packing by large force when a connected pipe is largely deviated in relation to a socket, and the seal pipe is easily damaged, as the case may be, the seal piece is inward drawn and torn with pipe insertion in a conventional one-touch packing. SOLUTION: A plurality of centering deviation regulating projecting parts 13 to 13 for restraining centering deviation of a connecting pipe 2 in relation to a second seal piece 12 are circumferentially provided on the inner surface of a packing main body 11. Since the connecting pipe 2 is approximately concentrically maintained in relation to an inner peripheral hole of the seal piece 12, the seal piece 12 is bonded to the pipe 2 over the whole circumference by moderate force. Accordingly, the seal piece 12 is not partially drawn inward by large force in inserting of the pipe 2. |
