Provided is a female terminal fitting that can realize a state in which an elastic contact piece stably engages a main body part. A female terminal fitting includes a tubular main body part and an elastic contact piece that is provided inside the main body part and deflectively deforms in the plate thickness direction. The main body part has a right side plate. The right side plate is provided with a right rear opening. An edge part of the right rear opening is provided with a first regulating part bent to the inner side of the main body part. The elastic contact piece has a rear side projecting part positioned in the right rear opening and a region opposing the first regulating part in the plate thickness direction of the elastic contact piece together with the rear side projecting part.

It is aimed to provide a connector capable of improving the reliability of connection detection. A connector is provided with a first housing and a second housing connectable to each other, a detector arranged movably to a standby position and a detection position with respect to the first housing, the detector being allowed to move to the detection position when the first and second housings are connected properly, and a biasing member accommodated in either one of the first and second housings. The biasing member accumulates a biasing force by being pressed by the detector moving toward the detection position.

A connector is provided with a first housing and a second housing connectable to each other, a detector arranged movably to a standby position and a detection position with respect to the first housing, a pair of second terminal fittings arranged in the second housing, and a shorting terminal arranged in the second housing to short-circuit the pair of second terminal fittings. The detector includes a releasing portion for releasing a short-circuit state of the pair of second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position.

A one-piece rubber plug () includes a main body () with insertion holes () and tubular projections () communicating with the insertion holes () and projecting from the rear surface of the main body (). Restricting surfaces () matchable with restriction areas () on the outer peripheries of the tubular projections () are formed on through holes () of a rear holder (). The rear holder () is displaced between a deformation permitting position where the restricting surfaces () are not in contact with the restriction areas () and where resilient radially expansive deformations of the tubular projections () are permitted and a deformation preventing position where radially expansive deformations of the tubular projections () are prevented by bringing the restricting surfaces () into contact with the restriction areas () substantially over the entire circumferences.
