Abstract A contact insertion-extraction tool for removing an electrical contact from a connector assembly. A pair of semi-cylindrical portions define a cylinder having an opening at the front end thereof. The rear ends of each of the portions are each secured to a bracket with alignment means on said bracket for assuring correct alignment of the semi-cylindrical portions. The alignment means may be formed of a tongue and groove arrangement on each of the brackets. Further, a tip protector may be provided to protect the front end of the portions when the tool is not in use, as well as to provide protection for the tool operator when the tool is in use.
