A safety quick connection for connecting a source of fluid to a working element has a body connectable to the fluid source, a fitting member connectable to the working element and movable relative to the body, and a locking member, the body, the feeding member and the locking member being formed so that under the action of fluid flowing through the connection from the fluid source to the working element a part of the body engages with a part of the locking member and prevents opening of the connection.
