ABSTRACT:
A connection device for blasting signal transmission tubing comprises a housing consisting of first and second hinged section (1, 2) provided with cooperating arcuate raised portions (3, 5) and grooves (4, 6) which, when the housing is closed, define first and second arcuate, circular-section channels, interconnected by a further channel (8). In use, first and second lengths of transmission tube are located in the arcuate channels and are partially cut by a blade (10) mounted in the connecting channel (8) to form apertures therein, whereby a portion of a blasting signal entering the connector via one of the tubes will spill out of that tube, traverse the connecting channel (8), and initiate a signal in each arm of the other tube.
