Abstract: An electrical terminal block is provided with a plurality of terminal-receiving cavities therein and a corresponding plurality of electrical terminal elements disposed within the terminal-receiving cavities. Each terminal-receiving cavity includes a protruding retention member extending into the terminal-receiving cavity. Each terminal element includes a chamfered key member thereon, which is adapted to be captured and to interlock with a complementary retention member during insertion of the terminal elements into their respective cavities. The retention members and their corresponding cooperatively engaging chamfered key members selectively provide means for securing or facilitating removal of the inserted terminal elements.
