Claims

[Scope of claim for utility model registration] Joining tongue piece 7 whose left and right edges are each Y-shaped,
8, a cylindrical-shaped unbonded part 4' is provided in the unbonded part 4 formed in a band shape in the width direction of the heat-shrinkable sheet main body 1 in the substantially central part thereof. The unbonded part 4' of the heat-shrinkable tube 8 having the above-mentioned heat-shrinkable tube 8 is inserted almost perpendicularly so as to match the width direction of the unbonded part 4 of the heat-shrinkable sheet main body 1, and each outer layer part and each inner layer part In the heat-shrinkable molded covering material constituted by the heat-shrinkable sheet main body 1 and the heat-shrinkable tube 3, which are fused and joined to each other, the heat-shrinkable sheet main body 1 and the heat-shrinkable tube 3 are Both unbonded parts 4 and 4' with the heat-shrinkable tube 3 are cut out from approximately the center, and a Y-shaped joint is made from the heat-shrinkable tube 3 for the branching part to one side of the center of the heat-shrinkable sheet main body part 1. A heat-shrinkable covering material for a T-shaped branch connection, characterized in that tongue pieces 10 and 11 are formed continuously.
