<p>The device has a clamping device for retaining a connecting unit (5), where the clamping device is movable parallel to a longitudinal direction of the connecting unit against the force of a spring. A distance sensor detects a magnitude of the displacement of the clamping device, and blocks the movement of the clamping device through an end of a signal conductor (1.2), when the clamping device reaches a base of a blind hole (5.1). The sensor activates a fixing unit (13), which connects the signal conductor and the connecting unit with each other transverse to the longitudinal direction.</p> |
