What is claimed is: 1. A female connector to be connected to a fluid delivery tube comprising: a cylindrical core member including a luer taper on an inner surface of a distal end portion of the core member, a tube bonding portion on an inner surface of a proximal end portion of the core member, and a flange at a distal end of the core member; a cylindrical housing mounted to an outer periphery of the core member without being fixed and having a male screw formed on an outer surface of the housing; and a stopper fixed at a predetermined position apart from the flange of the core member, wherein a distance (L1) between the flange and the stopper is equal to or larger than a length (L2) of the housing in an axial direction and a length (L3) between a proximal end of the housing and a distal end of the stopper when the female connector is connected to a male connector is smaller than a screwing distance of the male screw of the female connector into a female screw of the male connector. 2. A female connector according to claim 1, wherein the distance (L1) between the flange and the stopper is larger than the length (L2) of the housing in the axial direction when the female connector is connected to a male connector. 3. A female connector according to claim 1, wherein a projection is formed at an end of the housing facing the stopper and an engagement portion which can engage with the projection is formed at an end of the stopper facing the housing. 4. A female connector according to claim 1, wherein the housing includes wings on an outer surface of the housing. 5. A female connector according to claim 1, wherein the core member is formed of one material selected from the group consisting of vinyl chloride, polyurethane and polybutadiene and the housing is formed of one material selected from the group consisting of polypropylene and polycarbonate.
