Abstract:
A screw terminal with creep compensation comprises a pressure device enabling a clamping energy of the terminal to be stored. According to the invention, means for detecting the tightening torque enable the user to identify the force required for connection and to check that the creep is in fact compensated. The means for detecting comprise an element securedly affixed to the pressure device and an element securedly affixed to a wall of the housing in which the terminal is fitted, the distance between the two elements being determined by means enabling indicating means to be actuated when the distance is smaller than a threshold corresponding to a predetermined tightening torque.
