A powder charge operated setting tool includes a barrel (5) and a closing or breech member (8), both axially displaceable in a housing 1. Tensioning of a tension spring (18) for a firing pin (17) is made possible by means of a disengageable snap-in element 12 acting between housing 1 and closing member 8 by pressing the barrel 5 against the receiving material. The disengagement of the snap-in element 12 occurs only by overcoming a predetermined force acting counter to the setting direction which is generated by the gas pressure after a propellant charge 19 has been ignited.

Outil de fixation à charge de poudre comprenant un canon (5) et un dispositif de fermeture ou une culasse (8), tous deux mobiles à l'intérieur d'un boîtier (1). La mise en tension d'un ressort de tension (18) pour le percuteur (17) est rendue possible par un élément désengageable par pression (12) entre le boîtier (1) et le dispositif de fermeture (8) en appuyant le canon contre le matériau à travailler. Le désengagement de l'élément par pression (12) se produit seulement après que soit vaincue une force prédéterminée qui est opposée au sens d'installation et qui est produite par la pression des gaz après la mise à feu d'une charge propulsive (19).
