Abstract:
1. A signal tube connector ( 10 ) which includes a detonator-receiving body ( 12 ) with a longitudinal axis ( 14 ) and at least one retention member ( 40 , 42 ), the detonator-receiving body ( 12 ) and the retention member ( 40 , 42 ) including respective surfaces which oppose each other and which form, between the surfaces, a signal tube locating space ( 60 ), the retention member ( 40 , 42 ) being movable relative to the detonator-receiving body ( 12 ) to vary the position of one of the opposing surfaces relative to the other opposing surface, and at least one locking mechanism ( 50 , 52 ) which is operable to prevent movement of the retention member ( 40 , 42 ) relative to the detonator receiving body ( 12 ), characterised in that the retention member ( 40 , 42 ) in cross-section parallel to the longitudinal axis ( 14 ) has a dished shape with a curved section ( 54 ) which extends towards an opposing surface ( 56 ) of the detonator-receiving body ( 12 ), a central region of the curved section ( 54 ) being closest to the longitudinal axis ( 14 ) and adjacent regions of the curved section ( 54 ) moving away from the longitudinal axis ( 14 ).
