Abstract
Abstract A connector includes flexible hinge pieces molded of a synthetic resin, wherein each flexible hinge piece is caused to upwardly extend. When each side plate of a retainer is squeezed from above toward the rear end side of a recessed part formed on one side surface of a connector housing, a provisional engagement locking protuberance is fitted into the fore end side of an elongated hole, causing the fore edge of the side plate to be held between the provisional engagement locking protuberance and a normal engagement locking protuberance in the clamped state. The retainer is thus held in the provisionally engaged state. The hinge piece is folded in the connector housing, and the retainer positioned where each terminal piece can be inserted into and drawn from the corresponding terminal insert hole. When the retainer is further squeezed from above after the terminal piece is inserted into the terminal insert hole, a normal engagement locking protuberance is fitted into the fore end side of the elongated hole, causing the provisional engagement locking protuberance and the normal engagement locking protuberance to be engaged with the opposite ends of the elongated hole. The retainer is thus held in the normally engaged state.
