Abstract: A connector includes a terminal fitting to be inserted into a terminal accommodation chamber of a housing and a retainer attached to the housing and displaceable between a temporary locking position and a complete locking position. The retainer is formed with a resiliently deformable locking lance arranged to face the terminal accommodation chambers at the temporary locking position and a complete locking portion arranged to face the terminal accommodation chamber at the complete locking position and having a higher stiffness than the locking lance. The locking lance allows insertion of the terminal fitting into the terminal accommodation chamber by being resiliently deformed and temporarily holds the terminal fitting in a retained state by locking the terminal fitting in the terminal accommodation chamber. The complete locking portion holds the terminal fitting in a retained state by locking the terminal fitting inserted into the terminal accommodation chamber.
