SUBSTANCE: in connector of coupling for pipelines for fluid mediums there is a blocking element to block inserted part introduced into connector and control element for control of reliable blocking of inserted part. The control element is equipped with side spring levers springy in axial direction; levers have an engagement structure designed for engagement with an arresting structure; in the first control position without reliable blocking the inserted part, the engagement structure blocks transfer of the control element into the second control position. The inserted part actuates an executing structure made on each spring lever which brings the control element into the second control position whereat it is out of engagement with the inserted part. Consequently, the inserted part can also be removed from the connector due to actuation of the blocking element at the second control position of the control element.

SUBSTANCE: device for connection of two pipes includes an external thread located on the first pipe. A shutoff element with external shutoff profiles is installed on the second pipe of the pipeline with possibility of radial movement. On external thread there screwed is a coupling sleeve having an internal thread and internal shutoff profiles for engagement with the above external shutoff profiles. The coupling sleeve moves in the first axial direction to the first pipe by rotation on the external thread, when its internal profiles are in intermediate engagement with external profiles until this movement is restricted with thrust surfaces of internal and external profiles after possible axial gaps are chosen as a result of that first axial movement. Thrust surfaces have an inclination allowing to tighten the coupling sleeve in axial direction opposite to the first axial direction, at outward movement of external shutoff profiles in radial direction from position of intermediate engagement to position of further engagement with internal shutoff profiles.
