A tool for crimping cable shoe terminals having an affixing part and a contact part onto the ends of electrical conductors has a pair of jaws provided with at least one pair of co-operating crimping dies and hinged together by a pivot pin. On the same pivot pin is mounted a rocker arm carrying for each pair of crimping dies a chamber accommodating the contact part of a terminal to be crimped. The rocker arm is affected by a position-controlling force such as friction at the location of mounting, and by suitably located dog means so that it makes a move, after the crimping operation has been terminated, by which the terminal, now crimped on a conductor, is lifted from the crimping die so that it readily can be removed from the tool.
