A one-piece rubber plug (30) of the hybrid type is mounted at a rear side of a female housing (20).

The outer circumferential surfaces of sealing plugs (60) corresponding to larger terminals (20A) are resiliently brought into close contact with the inner circumferential surfaces of the large-diameter portions (34), whereas the outer circumferential surfaces of wires (33) are resiliently brought into close contact with the outer circumferential surfaces of wires (50) corresponding to small terminals (20B).
