a connection terminal for connecting an electrical device to a continuous electrical conductor such as a ground conductor includes a connector body with at least one terminal connection . each terminal connection includes a recess which extends in a direction of extension of the electrical conductor and a holding device to at least partially close the recess . the holding device is adjustable relative to the direction of extension of the electrical conductor from an open position in which the electrical conductor can be inserted into the recess to a closed position in which the holding device holds the electrical conductor in the recess . the holding device is either reversibly rotatable in a direction of rotation around an axis which extends in the direction of extension or reversibly displaceable in a sliding direction which extends transverse to the direction of extension . the terminal connection includes a clamping means device which clamps the electrical conductor and / or the holding device in the closed position .
