Abstract
The breech mechanism for a firearm is provided with a breech housing, a locking head connected to the barrel and having a radially inwardly directed conical locking shoulder oriented rearwardly of a cartridge carrier, and a substantially cylindrical breech block movable relative to the breech housing in a direction toward and away from the barrel. A locking sleeve concentrically surrounding the breech block and axially slidable relative thereto to a limited degree, is divided at its front end by a plurality of longitudinal slots into a plurality of spring tongues and carries at the free, front end of each spring tongue a locking element formed in one piece therewith and in the form of an annular segment. Each locking element has a radially outwardly directed cone segment bearing on the locking shoulder in a locking position and having on its front end a radially inwardly directed cone segment with which it bears on a spreading cone arranged in the vicinity of the front end of the breech block. There is further provided an actuating device which, with the breech closed, pushes the locking sleeve axially forwards relative to the breech block.
