Abstract
A ball coupler having a longitudinal axis and including a male tubular endpiece; a female tubular endpiece; and a tubular sleeve extending the female endpiece and presenting slots for forming a cage for retaining balls for blocking the male endpiece in the female endpiece. A grip is coaxial about the sleeve and mounted to turn about the longitudinal axis of the coupler between at least two angular positions relative to the sleeve, the grip having a housing for each ball. A resilient return device urges the grip into its first position, including in the grip, a ring that is constrained to turn with the grip and that is movable axially relative thereto.
