Abstract

In order to stop the calibration of the calibrating screw (10) for the bimetal element of a thermal circuit breaker mounted in a box (13), which screw (10) is accessible from outside through a hole in the box inside which the screw can be turned in one or other direction relative to a stationary, complementary internally threaded element in which the screw is engaged, a clip (1) has been provided which is arranged so as to lock itself in the hole of the box and to prevent any movement of the calibrated screw (10). <IMAGE>
