A connector block for retaining at least one shock tube in signal transfer relationship with a detonator. The connector block comprises a housing (2, 21) having a bore (4, 23) formed therein for receiving a detonator (6, 36) provided with a percussion-actuation end (7, 25), a shock tube retention means (8, 28) defining with the housing a slot (9, 29) for receiving therein at least one shock tube (10, 30) and holding the at least one shock tube in signal transfer relationship with the percussion-actuation end of the detonator present in the bore, the slot having an entrance (12, 32) for allowing insertion of the at least one shock tube into the slot, and a flexible and resilient closure member (11, 31) or an inflexible closure member (50) pivotable on a sprung hinge (51) extending partially or fully into the entrance. The closure member and the shock tube retention means resiliently flex to allow entry of the at least one shock tube through the entrance and into the slot, the closure member flexing through a distance at least 30% the diameter of the shock tube.

The invention claimed is: 1. A connector block for retaining at least one shock tube in signal transfer relationship with a detonator, the connector block comprising: a housing having an axial bore formed therethrough for receiving a detonator provided with a percussion-actuation end and a base charge disposed within the percussion-actuation end, the bore having an insertion end for receiving a detonator and a signal transmission end axially opposite the insertion end for positioning the percussion-actuation end of a detonator in signal transfer relationship with at least one shock tube; a rigid shock tube retention means integral with the housing and extending to axially overlie the signal transmission end of said bore, the shock tube retention means defining with the housing a slot for receiving therein at least one shock tube and to hold said at least one shock tube in signal transfer relationship with said percussion-actuation end of a detonator when present in said bore, said slot having an entrance for allowing insertion of shock tubes into said slot; and a flexible and resilient closure member integral with the housing and separate from the shock tube retention means, the closure member extending from said housing into said entrance, and being biased to partially or fully close said entrance, such that the entrance in the biased condition of the closure member is narrower than the slot; wherein said rigid shock tube retention means has a flexibility that is less than the flexibility of the closure member so that said closure member resiliently flexes away from said entrance and said biased position to allow entry of at least one shock tube through said entrance and into said slot, and said shock tube retention means undergoes no flexing when at least one shock tube is caused to be inserted into said slot. 2. The connector block according to claim 1, wherein said connector block is configured to permit entry of at least one shock tube by applying an insertional force of less than about 45 Newtons. 3. The connector block according to claim 1, wherein said closure member prevents inadvertent removal of shock tubes from said slot. 4. The connector block according to claim 1, wherein said closure member assists in the retention of any shock tube located within the slot adjacent to the entrance by contacting the shock tube. 5. The connector block according to claim 1, wherein the connector block comprises a plastic material. 6. The connector block according to claim 5, wherein the shock tube retention means comprises a first plastic material, and the flexible and resilient closure member comprises a second plastic material. 7. The connector block according to claim 1, wherein the flexible and resilient closure member comprises a metal. 8. The connector block according to claim 7, wherein the metal is a metal insert, and the metal insert is partially or completely enveloped in a plastic material. 9. The connector block according to claim 1, wherein entry of at least one shock tube into said slot induces an audible click. 10. The connector block according to claim 1, wherein the closure member extends partially or fully into said entrance at an angle of from about 45° to about 135° relative to the axis of the bore. 11. The connector block according to claim 10, wherein the closure member extends partially or fully into said entrance at an angle of from about 45° to about 90° relative to the axis of the bore. 12. The connector block according to claim 1, wherein the connector block further comprises: a positioning membrane for positioning the percussion-actuation end of a detonator in signal transfer relationship with shock tubes located in said slot. 13. The connector block according to claim 1, wherein the connector block further comprises: a shock tube insertion guide integral with the shock tube retention means, the shock tube insertion guide defining with said closure member a receiving space for guiding at least one shock tube to said entrance of said slot. 14. The connector block according to claim 13, wherein the receiving space narrows at an end adjacent said entrance of said slot. 15. The connector block according to claim 1, wherein the slot can accommodate up to six shock tubes. 16. The connector block according to claim 1, wherein the closure member flexes through a first distance at least two times greater than a second distance that the shock tube retention means flexes through when at least one shock tube is caused to be inserted into said slot. 17. The connector block according to claim 1, wherein the closure member flexes through a first distance more than two times greater than a second distance that the shock tube retention means flexes through when at least one shock tube is caused to be inserted into said slot. 18. A connector block for retaining at least one shock tube in signal transfer relationship with a detonator, the connector block comprising: a housing having an axial bore formed therethrough for receiving a detonator provided with a percussion-actuation end and a base charge disposed within the percussion-actuation end, the bore having an insertion end for receiving a detonator and a signal transmission end axially opposite the insertion end for positioning the percussion-actuation end of a detonator in signal transfer relationship with at least one shock tube; a substantially inflexible shock tube retention means integral with the housing and extending to axially overlie the signal transmission end of the bore, the shock tube retention means defining with the housing a slot for receiving therein at least one shock tube and to hold the at least one shock tube in signal transfer relationship with the percussion-actuation end of a detonator when present in the bore, the slot having an entrance for allowing insertion of shock tubes into the slot; and a flexible and resilient closure member integral with the housing and separate from the shock tube retention means, the closure member extending from the housing into the entrance, and being biased to partially or fully close the entrance, such that the entrance in the biased condition of the closure member is narrower than the slot, the closure member being wider in dimension at its base where it attaches to the housing than where the closure member extends into the entrance of the slot so that the closure member is flexible at the slot entrance; wherein the shock tube retention means has a limited flexibility that is less than the flexibility of the closure member so that the closure member resiliently flexes away from the entrance and the biased position to allow entry of at least one shock tube through the entrance and into the slot, and the shock tube retention means undergoes little or no flexing when at least one shock tube is caused to be inserted into the slot.
