The connector comprises an inner structure and an outer housing. The inner structure comprises a fit portion, which is fit to a mating fit portion of a mating connector under a mated state, and a cable-holding portion configured to hold a jacket of a cable. The fit portion comprises terminals, a holding member holding the terminals and a shell enclosing the terminals and the holding member. The cable-holding portion is located rearward of the fit portion in a front-rear direction (X-direction). The outer housing has a front holding portion and a rear holding portion. The front holding portion holds the shell to prevent a movement of the fit portion in a perpendicular plane (YZ-plane) perpendicular to the front-rear direction. The rear holding portion is located rearward of the front holding portion and holds the cable-holding portion to prevent a movement of the cable-holding portion in the perpendicular plane.
