PROBLEM TO BE SOLVED: To provide a sealing tool which prohibits a joint from removing from a joint connection configured by connecting a plurality of joints and at the same time can distinguish whether the joints are removed.SOLUTION: The sealing tool 50 is used for a connection type header 12 which is configured by connecting a header base body 14 having a main pipe portion 16, the insertion portion 32 provided therein and a retention release means which retains a pipe portion 26 in an insertion portion 32 when a pipe portion 26 of the main pipe portion 16 disposed within the insertion portion 32 and connected to the insertion portion 32 is inserted and moreover which releases the retention of the pipe portion 26 when a pressure is applied through a clearance between the insertion portion 32 and the pipe portion 26 connected with the insertion portion 32. The sealing tool 50 makes it possible to prohibit the header base body 14 from being removed from the connection type header 12 and to distinguish removal of the joint because it is provided with a breakable annulus 50A which is disposed on the pipe portion 26 so as to seal the clearance between the insertion portion 32 and the pipe portion 26 connected thereto it and a fixed means which fixes the annulus 50A to the pipe portion 26 connected to the insertion portion 32. |
