The versions of the inventions relate to mining, in particular to connection of sunk pneumatic hammer mechanisms to the crowns for well drilling. The connection has the bush (1), the tail of the drill crown (2) equipped with long channels (3) and (4) with driving solids of revolution placed in those. Those are arranged as rollers (5) and fixed in the bush (1) with stopper ring (6) in the channel (7) spring is installed for locking body, this is arranged as a cylindrical stopper (8). The stopper (8) is installed with possibility of turn with respect to its axis and is arranged with segment recess (10), the axis of this one is displaced with respect to the axis of the tail element of the drill crown (2). The tail element of the drill crown (2) is arranged with a circular reboring (11) and long flat (12), and the bush (1) has a circular boss (13), this interacts with the circular reboring (11). Depth of the segment recess (10) is equal to the depth of the long flat (12). The stopper (8) has a slot (14) placed at its end at the side opposite to the segment recess (10), and the bush (1) has pin (15) interacting with the slot (14). The stopper (8) and the base of the channel (7) are equipped with depressions (16) and (17) for spring (9). The bush (1) has circular groove (18) for the stopper ring (6). The other version of the connection is distinguished by the design of the stopper (8). It has radial slant (19) placed at its end at side opposite to the segment recess (10) and interacts with the roller (5). This invention promotes increase of reliability and simplification of its assembling and disassembling of the joint.
