Abstract
The invention concerns a fastening tool employing a caseless munition. The tool includes a cavity for the munition, or explosive chamber, constituting a high-pressure chamber communicating with a low-pressure expansion chamber through at least one passage. The cavity for the munition, or explosive chamber, is formed radially in the very body of the breech, access thereto for loading being located on the periphery of said breech. It is possible to close said access after loading with a closing member, and the passage or passages putting the munition cavity in communication with the low-pressure chamber are formed in said breech.
