<p>An object of the present invention is to provide a connector suitable for the miniaturization. <??>A female housing 20 made of a synthetic resin is formed with cavities 22 for accommodating female terminal fittings 21, and locking portions 24 engageable with the female terminal fittings 21 to retain them are provided in the cavities 22. Each locking portion 24 projects out from an upper surface 20a or bottom surface 20b of the female housing 20 during the resilient deformation. A lock arm 40 for holding a mating male connector M in a connected state is mounted on the female housing 20. The lock arm 40 is made of a metallic piece and includes a press-in portion 42 which can be pressed into press-in grooves 30 of the female housing 20. The lock arm 40 is so arranged as to face the locking portions 24O and can be retracted into deformation spaces 33O for the locking portions 24O during the resilient deformation. <IMAGE></p>
