摘要

The articulated pipe connection comprises a female connector (3) with a spherical inner surface (7) and a male connector (9) with a shoulder (13) near its end. A sleeve (11) with a spherical outer contour fits over the male connector. A spring (15) mounted between the two connectors biases the shoulder against the sleeve and the sleeve against the inner surface of the female connector. the spring is not attached to the connectors and allows the pipes to, rotate with respect to each other.
