Abstract
A safety device for a setting gun used for driving fastening elements into a receiving material by means of an explosive charge, utilizes two arm swivel levers pivotally mounted on the forward end of the gun housing for locking the gun barrel out of the firing position. One arm of each lever forms a catch arranged to block the movement of the barrel into the firing position until the other arm presses against the receiving material and causes the lever to pivot, displacing the catch from its blocking position. Normally, the swivel levers are spring biased into position to prevent movement of the barrel into the firing position.
