Problems solved by technology

However, at this time, there are new problems as follows: the rubber tube 902 attached to the tubular part 901 is easy to fall off, or the liquid leaks from between the tube 901 and the rubber tube 902
[0011] In addition, depending on the shape or size of the outer peripheral surface of the tubular portion 901 of the male connector, there is a problem that it may take time to insert the tubular portion 901 into the rubber tube 902.

Abstract

A female connector (100) to be connected to a male connector (170) having a tubular section (172), out of which a liquid-like substance flows, is disclosed. The female connector has an adaptor (110) installed on the outer peripheral surface of the tubular section, and a handle (120) fitted on the adaptor. The adaptor has a tube-shaped section (112) having an opening (119a) at one end. The tube-shaped section includes an insertion section (119) into which the tubular section is inserted from the opening, and the insertion section has flexibility and elasticity. The handle has a rigidity higher than that of the insertion section of the adaptor. There is provided movement limitation means that limits a range in which the handle is capable of moving relative to the adaptor from an end of the adaptor on an opposite side of the opening to an end thereof on the opening side in a direction of a center axis (111) of the adaptor.
