The invention relates to a packing member for water-tightening a pipe and, more particularly, to a packing member which is inserted into a housing and inserted into the outside of a pipe, comprising: an inner circumferential portion (261) which is inserted into the outside of the pipe; an outer circumferential portion (262) which is inserted into the housing and is connected to the inner circumferential portion (261) at one side thereof so as to form a fluid accommodating portion (265) between the housing and the outer circumferential portion (262); and the fluid accommodating portion (265) for accommodating a fluid which flows inside the pipe, wherein the inner circumferential portion (261) comes into close contact with the outer side surface of the pipe by means of the pressure of the accommodated fluid to thereby form a water-tight structure with the pipe. According to the present invention, the packing member has a support portion, whereby it is possible to maintain the shape of the packing member even when the packing member is exposed to a high-pressure fluid environment when connected to the pipe or after installation, thereby providing a highly-efficient water-tight structure. |
