Quick connection coupling, particularly for attaching tools on turret arm of tyre mounting-dismounting machines

A quick-connection coupling, particularly for tools of tyre-dismounting machines (5), of the type having at least one elongated element (3) with a longitudinal axis (L) which is movable with respect to a stationary column (4) for mounting/dismounting a tyre onto/from a wheel rim. The coupling comprises at least one male element (6) and at least one female element (7), which may be coupled respectively with the elongated element (3) and at least one tool (2) along said longitudinal axis (L). The male element (6) and female element (7) have complementary conical and/or frustoconical profiles.
