The present invention relates to a heat shrinkable connection tube for coupling pipes and, more specifically, relates to a heat shrinkable connection tube for coupling pipes allowing the pipes to be coupled as an exothermic shrink part (31) heated and contracted through chemical exothermic reaction in exothermic units (4) included inside the exothermic shrink part (31) in a state where a heat shrinkable connection tube (3) including a pipe coupling connection part (30) and the exothermic shrink part (31) covers the ends of a first wire pipe (1) and a second wire pipe (2) to be connected to the first wire pipe (1) and the second wire pipe (2) required to be connected with each other. The heat shrinkable connection tube comprises: reaction liquid pockets (40) and exothermic body pockets (41). The reaction liquid pockets (40) allow a plurality of exothermic units (4) to be embedded in an interior of the exothermic shrink part (31) in such a manner that the exothermic units (4) are arranged in a radial direction to continuously be connected to each other, has cutting straps (42) positioned on each exterior thereof to be pulled by applying an outer pressure, and stores a reaction liquid (W) to allow the stored reaction liquid (W) to flow out when the reaction liquid packets (40) are torn by the cutting straps (42). The exothermic body pockets (41) are arranged to be in close contact with the reaction liquid pockets (40) and stores exothermic bodies (H) in a powder form, and the exothermic bodies (H) reacting to the reaction liquid (W) flowing out from the reaction liquid pockets (40) to generate heat. The cutting straps (42) included in each reaction liquid pocket (40) of the exothermic units (4) are branched from one pulling strap (50) to be connected. One side end of the pulling strap (50) is exposed to the outside through a pulling strap exposing an opening (33) included in one side of the exothermic shrink part (31). |
