A connector comprises a synthetic resin plug 11 fitted to an opening portion 1a of a container 1 that stores a liquid, and a socket 13 for connection to the plug 11. The plug 11 comprises, a lid body 14 secured in a fluid tight manner to the opening portion 1a, a plug portion 16 provided on the lid body 14 and connectable to the socket 13, and a siphon tube 17 extending downward from a lower portion of the lid body 14 such that when the lid body 14 is secured to the opening portion 1a, a lower end is arranged near a bottom of the container 1. The siphon tube 17 comprises a tube integrally formed with the lid body 14. As a result, when the liquid inside the container 1 is drawn out, gas leakage from the siphon tube 17 can be reliably prevented, so that erroneous detection of an "empty" detection can be reliably prevented and the liquid completely used up.
