A tool attachment for installing key-locking inserts, and a kit including such a tool attachment. For installing the key-locking insert, which is configured to be locked by a key, the tool attachment can be mounted on a power head, and connected to a pneumatic power supply, and includes a tightening torque transmission device, tightening the insert, and, in a casing, a key striker device configured to crimp the key onto the insert when crimping pressure is applied to the key by the pneumatic power supply. The striker device includes plural plates that are substantially perpendicular to the tightening axis. Crimping pressure applied suddenly to the plates inside the casing drives the key striker device and to crimp the keys. The tool attachment does not include moving mechanical parts, and is highly reliable. |

1-8. (canceled) |
| Claim: |
9. A tool attachment for installing a key-locking insert configured to be locked by a key, which tool attachment is configured to be mounted on a power head, and to be connected to a pneumatic power supply, the tool attachment comprising: a tightening torque transmission device configured to tighten the insert along a tightening axis when tightening torque is applied to the device by the power head; and a key striker device housed in a casing, configured to crimp the key onto the insert when crimping pressure is applied to the key by the pneumatic power supply, wherein the striker device includes a plurality of plates that are substantially perpendicular to the tightening axis, that are at least partially superposed therealong, and that are configured, under effect of the crimping pressure applied suddenly to them, to drive the striker device and to enable the key to be crimped. |
| Claim: |
10. A tool attachment for installing a key-locking insert according to claim 9, in which the striker device includes parts that are stationary relative to one another. |
| Claim: |
11. A tool attachment for installing a key-locking insert according to claim 9, in which the striker device includes a sleeve-shaped portion mounted to slide coaxially about a shaft transmitting the tightening torque, the plates being disposed in the casing around the sleeve-shaped portion, at least one of the plates being removable relative to the sleeve-shaped portion. |
| Claim: |
12. A tool attachment for installing a key-locking insert according to claim 9, further comprising return means for urging back the striker device, which means make it possible, after a strike, to cause the striker device to return to an initial position making it possible for another strike to take place. |
| Claim: |
13. A tool attachment for installing a key-locking insert according to claim 12, in which the return means for urging back the striker device comprises at least one spring. |
| Claim: |
14. A tool attachment for installing a key-locking insert according to claim 9, further comprising at least one air duct provided in one or more walls of the casing configured to put the plates under air pressure during the strike. |
| Claim: |
15. A tool attachment for installing a key-locking device according to claim 9, in which the striker device has exactly three plates. |
| Claim: |
16. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 9. |
| Claim: |
17. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 10. |
| Claim: |
18. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 11. |
| Claim: |
19. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 12. |
| Claim: |
20. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 13. |
| Claim: |
21. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 14. |
| Claim: |
22. A tightening and key-installation kit, comprising a power head and a tool attachment according to claim 15. |
