A connector 10 and tube set for use in a medical procedure e.g. a water bottle for use with an endoscope, the connector 10 connects a tube set to a container, comprising a collar 12 connectable to a container, a cap 14 comprising at least one opening 30 for receiving a tube of a tube set, and an annular seal 16, wherein the cap 14 is located in the collar 12 between an inner surface of the collar 12 and the seal 16, and wherein the cap 14 is rotatable relative to the collar 12. The cap 14 can comprise four openings. The tubes can supply both gas and liquid. The device allows one bottle to replace two bottles and avoids twisting or straining tubes connected through the cap.
