In the closed position of the bolt, the front hook 2 of the barrel is located at a certain distance from the rod 4 of the hinge, while the rear hook 5 of the barrel is applied against the corresponding bevelled surface of the cross-piece of the bolt element 3 and comprises a locking tooth whose wedge angle is substantially the same as that of the catch 7. The extraction rod 50, 51 is provided above the rear hook 5 of the barrel and cooperates with an operating element at its front end. The blade 14 of the trigger can rotate about an axis 15 which is disposed closer to the percussion base of the bolt element 3 than the rod 22 of the axis of the percussion piece 18 whose arming tooth 24, in the armed position, rests on the stop end 44 of the branch 41 which extends upwards from the blade 14 of the trigger. <IMAGE>
