ABSTRACT:
A snap-on coupling for mounting accessories on the end of a cylindrical gun barrel characterized by its ability to be quickly operated. The gun barrel is provided with an annular groove axially spaced from the gun barrel end, and an adapter includes a bore receiving the gun barrel end region and radially displaceable ball detents in the adapter are received within the barrel groove upon radial alignment. A spring biased detent operator collar axially displaceably mounted on the adapter controls the radial position of the ball detents wherein manual axial displacement of the detent operating collar may be accomplished quickly with one hand. In an embodiment of the invention, a ball detent retainer sleeve within the adapter bore is automatically displaced by the gun barrel end upon placing the adapter on the gun barrel permitting the ball detents to be received within the barrel groove upon alignment, and the ball retainer sleeve eliminates the necessity of displacing the collar during insertion of the adapter on the gun barrel.
