<p>This invention concerns injection guns, particularly for pressurised application of material from a container coupled to a ram of the gun. A coupling between the ram 11 and the container 12 is proposed that is comprised of three coaxial parts 21, 22, 23 that are relatively axially movable over a region of mutual overlap whereat, during such relative axial movement, an interlocking part or parts, such as balls 24, transfers between interlocking together of one pair of coaxial parts and interlocking together of another pair of coaxial parts.</p> |
