A connection device for conductors has one or more single conductor terminals which are formed as direct plug connections. Each conductor terminal has a metal contact element such as a metal clamping cage, a spring support made of a non-conductive material such as plastic, and a clamping spring. Each of the spring supports is placed on at least one corresponding receiving element made of a non-conductive material.

An electrical connector comprise an insulating housing, a spring clip disposed in the insulating housing, and control pieces for opening the spring clip. The insulating housing comprises outer wall sections separately corresponding to wire inserting spaces defined inside the insulating housing. Each outer wall section at least partially extends into a gap formed by a corresponding control piece when the control pieces are switched to a closed state. Moving spaces are defined on an outside of two sides of each of the outer wall sections. The control pieces perform an opening operation and a closing operation in the moving spaces. When the control pieces are in an open state, the spring clip is observed along the moving spaces. Along a width direction of the spring clip, the spring clip is at least partially exposed in projections of the moving spaces along an up-down direction of the moving spaces.
