PURPOSE: A connection structure of precision explosive tube and connector is provided to prevent the precision explosive tube from being unstably supported by a plurality of existing supporting elements by forming the supporting elements in a one body shape and completely safely perform blasting operation by using decoupling process. CONSTITUTION: In a connection structure in which connectors(20) are connected to front and rear sides of precision explosive tube(10), the connection structure comprises a connection part(40) for connecting the precision explosive tube to the connectors in such a way that the precision explosive tube is capable of performing locking operation and translation operation after inserting one end part of the precision explosive tube onto the inner circumferential surface of the connectors in a direction for connecting the precision explosive tube to the connectors, wherein a supporting body comprising a plurality of supporting elements(30) slantly formed to a certain angle in a radial direction is integrally formed at one end part of the connectors, and wherein the connection part comprises a truncated conical locking protrusion(41) integrally formed at both end parts of the precision explosive tube, and a truncated conical locking projection(43) integrally formed at both end parts of the connectors.
