A connector for a nondestructing blasting signal transmission tube including a housing; for engaging the extensions of at least two signal transmission tubes in adjacent relationship, the housing serving to establish a signal path permitting direct signal communication between openings in the adjacent portions of the signal transmission tubes. Preferably the connector includes a suitable device for cutting the adjacent portions of at least one of the signal transmission tubes to expose a portion of the reactive interior of the tube. Also, a method of connecting at least two signal transmission tubes by securing portions of the signal transmission tube in adjacent relationship to another; establishing a signal path between the adjacent portions of the signal transmission tubes; and cutting each of the adjacent signal transmission tubes to expose a sufficient portion of the interior of the tubes to permit direct signal communication between each of the tubes.
