An impact initiated attachment device for attachment to a target, comprises a housing having a front face which abuts against the target in use, one or more fasteners, a drive mechanism for driving the fasteners(s) from a first position within the housing to a second position protruding from the front face of the housing, and a trigger mechanism for triggering activation of the drive mechanism comprising a trigger extending from the front face of the housing. The device is particularly useful in Explosive Ordnance Disposal (EOD) and demolition for attaching one or more disrupters to a target for disposal.

1. An attachment device for attachment to a target, the device comprising: a housing having a front face which abuts against the target in use,one or more fasteners,a drive mechanism for driving the fastener(s) from a first position within the housing to a second position protruding from the front face of the housing, anda trigger mechanism for triggering activation of the drive mechanism comprising a trigger extending from the front face of the housing and connected to the drive mechanism such that pressure on the trigger towards the front face of the housing causes activation of the drive mechanism to drive the fastener(s) from the first position to the second position, wherein the trigger mechanism is non-electrically operatively connected to the drive mechanism. 2. An attachment device as claimed in claim 1 in which the drive mechanism is arranged to detonate a cartridge containing explosive material to cause the fastener(s) to be driven to the second position. 3. An attachment device as claimed in claim 1 in which the drive mechanism includes a striker within the housing which is forced in a direction towards the front face in response to pressure on the trigger from outside the housing towards the front face. 4. An attachment device as claimed in claim 3 in which the drive mechanism is arranged to detonate a cartridge containing explosive material to cause the fastener(s) to be driven to the second position and the striker is arranged to strike the cartridge and thereby detonate the explosive. 5. An attachment device as claimed in claim 1 comprising a plurality of fasteners in which each fastener is an elongate member having a laterally extending rear portion which is captured within the housing when the fastener is in the second position. 6. An attachment device according to claim 5 in which each fastener has a generally cylindrical forward portion and the laterally extending portion provides an annular shoulder to abut against a portion of the interior of the housing. 7. A device as claimed in claim 1 in which each of the one or more fastener is shaped to resist its removal from an object after insertion. 8. A device as claimed in claim 1 in which each of the one or more fastener comprises barbs to resist its removal from an object after insertion. 9. A device as claimed in claim 1 in which each of the one or more fastener is harpoon shaped. 10. An attachment device as claimed in claim 1 comprising a fastening mechanism having fastened and unfastened configurations in which the activation of the trigger causes the fastening mechanism to move from the fastened configuration to the unfastened configuration. 11. An attachment device as claimed in claim 10 in which the fastening mechanism comprises a member movable in response to activation of the trigger from the closed position to an open position. 12. An attachment device as claimed in claim 11 wherein in the closed position the member bridges an opening in the housing and in the open position the member is at least partially retracted from the opening. 13. An attachment device as claimed in claim 11 wherein the member comprises a bolt. 14. An attachment device as claimed in claim 10 in which the fastening mechanism comprises a member movable in response to activation of the trigger from a closed position to an open position, wherein the member is driven by the drive mechanism. 15. An attachment device as claimed in claim 1 having attached thereto one or more secondary devices for attachment to the target. 16. An assembly as claimed in claim 15 comprising a handle joining the device and the secondary device(s). 17. An assembly as claimed in claim 15 comprising multiple attachment devices and/or multiple releasable fastening devices. 18. As assembly as claimed in claim 15 including multiple attachment devices and/or multiple releasable fastening devices and multiple secondary devices. 19. An assembly as claimed in claim 15 in which the one or more secondary devices comprise one or more disruptors. 20. An assembly as claimed in claim 19 in which the one or each disruptor has a generally cone shaped forward section which is fixed with respect to the device such that the trigger of the device is level with or slightly forward of the front of the cone-shaped section of the disruptor(s). 21. An assembly as claimed in claim 20 in which the disruptor(s) and device(s) are fixed in such as way as to permit rotation of the disruptors with respect to the device(s). 22. An assembly as claimed in claim 20 comprising multiple devices and multiple disruptors arranged in parallel around the collar or cowl. 23. An assembly as claimed in claim 19 comprising a collar or cowl to which the device(s) and the one or more disruptors are attached. 24. An assembly as claimed in claim 15 including one or more buoyancy aids whereby to render the overall density of the assembly higher than that of water. 25. A disruption system comprising an assembly as claimed in 15 and a detonation line for attachment to the or each disruptor. 26. A disruption system as claimed in claim 25 comprising a dispenser for the detonation line. 27. A disruption system as claimed in claim 25 including a floating device supporting the dispenser. 28. A disruption system as claimed in claim 25 in which the detonation line comprises a tube filled with explosive material. 29. A disruption system as claimed in any of claim 25 further comprising a detonator initiation device. 30. A disruption system as claimed in claim 29 in which the detonator initiation device is remotely operable.
