A multi-pole connector has a first movable or plug-in connector member (30) with a plurality of electric contacts (131) supported by a terminal strip (31). The electric contacts are arranged in a pattern. The movable member (30) is designed to be mechanically and electrically coupled to a framework (1) which includes a second stationary, spring-biased connector member (5) which has at least one terminal strip (4, 4′) with a plurality of electric contact terminals (104, 104′) thereon, in the form of islands of material arranged in the same pattern. The movable member (30) is to be inserted into a fixed slide guide (103) and the connector member (5) is urged by springs (7) to bring terminal strips (4, 4′) into an electrical connection position with movable member (30) and a rotatable shaft (106) with cam (306) is used to move the stationary member (5) away from such position, to thereby permit release of the movable member (30).
