A steering and support handle for a wheeled luggage case is operatively pivotably connected to the wheeled luggage case to pivot to an operative or extended position in front of the case or to an inoperative or closed position adjoining the case. Means operative on the pivoted end of the handle biases the handle to maintain the operative position upon movement of the handle into the operative position and biases the handle to maintain the inoperative position upon movement of the handle into the inoperative position. The pivoted end of the handle is connected to the case by connecting means which provides a shoulder which is contacted by a surface on the pivoted end of the handle when the handle is moved to the operative position. The handle is T-shaped and its crossed end piece can be conveniently gripped in the hand of the user. The handle is preferably located in an indented marginal area at the closure location of the two opposed case halves or shells.
