In an explosive charge-driven fastening element setting gun having a casing and a muzzle tube axially displaceably mounted in the casing, a damping housing is arranged to receive explosive gases passing laterally out of the gun. The damping housing surrounds the gun and is formed of two parts, one fitting into the other in a telescoping manner. One part is attached to the muzzle tube and the other part is fixed to the casing. Packing is secured to one of the parts and extends into contact with the other part in the region where the parts are telescopically fitted together. |
