A spring fixture (1) is provided for quickly installing or uninstalling a coil spring (36) in or from an electrical connector (3). The fixture includes an operation member (11) having a generally cylindrical handle (12) at an end thereof and an action member (16) assembled on an opposite end of the operation member by a screw cap (18). The action member defines a recess (1620) thereby forming a semi-circular bottom wall (1622) and a semi-circular inner wall (1624). During installing or removing the spring, the spring is received in the recess and surrounded by the inner wall. A method of using the fixture to install and remove the spring is also provided.
