The invention provides a shock tube connector block (1) comprising a hollow body providing an enclosure (6) affording transmission or propagation of a shock wave from a shock tube inlet (4) mounting to multiple shock tube outlet (5) mountings arranged to support a plurality of ends of outgoing shock tubes in suitable proximity to a bare end of an incoming shock tube. The mountings (4, 5) are provided in passages for respective tubes and each mounting (4, 5) includes an outwardly facing shoulder for location of an inner end of a shock tube (14), non-return tube securing means, and a shock tube (14) engaging watertight seal (16). The body is preferably produced in two halves (2, 3) from a single mould with a seal circumferential to the enclosure locatable therebetween and ultrasonically welded together. The invention extends to an associated method of providing a manifold branch in a shock tube (14), which comprises supporting a bare end of an incoming shock tube (14) in an enclosed body in dose proximity to ends of a plurality of outgoing shock tubes (14). |
