PROBLEM TO BE SOLVED: To reduce an operational force of coupling between a male side connector and female side connector, and simplify a coupling operation. SOLUTION: Into the outside housing 18 of a female side connector 12, an inside housing 19 with plural stages and a push operation transferring member 20 are fitted, wherein each time this push operation transferring member 20 is operated from outside, the engaging relationship with each stage of the inside housing 19 is changed, and thus by making the push operation force loaded on the outside housing 18 convey to the inside housing 19 sequentially, the outside housing 18 and the push operation transferring member 20 are pushed and operated in turn, causing the inside housing 19 with multiple stages to be connected to the male side connector 11, sequentially.
