To provide a connector provided with a retainer which can prevent a retainer insertion hole from being exposed to the outside and has a strong force for retaining terminal fittings. A pair of insertion portions 41, 42 having different lengths extend in parallel from a base portion 43 of a retainer 40, and tapered surfaces 32, 33 for guiding the respective insertion portions 41, 42 in a direction oblique to the insertion direction of terminal fittings 20 are provided at the back of a pair of insertion holes 30, 31 formed in a housing 10 in conformity with the insertion portions 41, 42. When the retainer 40 is guided in the oblique direction, lock projections 45 provided on the retainer 40 directly lock the terminal fittings 20. Since the terminal fittings 20 are directly locked by the retainer 40 in this connector, they can be retained with a strong force. Further, since the insertion holes 30, 31 are open in the front surface of the housing 10, they are not exposed to the outside by being covered by a mating connector.
