Sterile connector

A medical device with a connector comprising:

• a first part and a second part, each provided with
• a contact surface and at least one non-contact surface facing away from the contact surface,
• at least one opening in the contact surface having a fluid connection to at least one opening of the non-contact surface,
• a releasable covering of the opening in the contact surface, and
• complementary means for mechanically coupling the parts at the contact surfaces to form the connector;
• and
• a medical tubing set, comprising at least one freeze bag and at least one tube, wherein the at least one freeze bag is coupled to the connector and the at least one tube, wherein the freeze bag comprises at least one recess into which the connector is inserted, with the freeze bag and connector in fluid communication within the recess;
• and
• characterized in that the complementary means for mechanically coupling the parts are configured to mechanically interlock with each other by counter-rotation of both the first and second parts about a single rotational axis which is orthogonal to the contact surfaces;
• and the openings in the contact surfaces are configured to be brought to match at least in part to provide fluid communication through the openings by counter-rotation of both the first and second parts about the rotational axis, wherein the openings in the contact surfaces of the first and second parts are not located in the rotational axis of the first and second parts which is defined by the centre of the counter-rotation of the first and second parts during coupling.
