FIELD: machine building.
SUBSTANCE: point includes case and retention element to retain the case with simultaneous interaction with it, in order to make it possible for the case to rotate in it around at least one axis. The case has through channels, every of which has the first and second holes, at the same time the first hole provides for passage of fluid through it from one of pipelines, and two pairs of male elements, every of which is installed in one of case channels. Male element may independently rotate in the channel and prevents leakage of fluid medium outside, at the same time each male element has the nozzle connected to pipeline in according hole of channel and additionally has a system of channels providing for passage of hydraulic fluid medium between a pair of pipelines connected to nozzle. The case has the channel in order to make it possible for fluid medium to pass between mutually joined pipelines.
EFFECT: invention prevents twisting on mutually joined pipelines in process of work with moving equipment.
