Les tenons de pivotement 14 s'engagent dans des ouvertures de pivotement 16 qui vent realisees dans la partie basse des parois laterales 18 de la partie superieure 6. Pour limiter le mouvement de pivotement du couvercle 8 et pour maintenir le couvercle 8 dans la position rabattue, des rebords de butee 20 realises en extremite sur les pastes de palier 10 viennent en contact sur des rebords de contre-butee 22 realises sur la partie superieure 6 en retrait par rapport aux parois laterales 18. Les rebords de contre-butee 22 vent munis d'une pente chanfreinee 24 qui stetend de la paroi laterale 18 voisine respective sous un angle obtus, par exemple 150 . Lors d'une sollicitation supplementaire du couvercle 8 contre les rebords de contre-butee 22, leurs pentes 24 provoquent un ecartement lateral des pastes de palier 10, dirige vers ltexterieur, de sorte que les tenons de pivotement 14 vent ensuite desenclenches hors des ouvertures de pivotement 16, ce qui permet ainsi de retirer le couvercle de la partie  Pivot pins 14 wind projecting inwards from the bearing steps 10. The pivot pins 14 engage in pivot openings 16 which are made in the lower part of the side walls 18 of the upper part 6. To limit the pivoting movement of the cover 8 and to keep the cover 8 in the folded position, stop flanges 20 produced at the end on the bearing steps 10 come into contact with counter flanges 22 produced on the upper part 6 set back with respect to the lateral walls 18. The counter-flanges 22 are provided with a chamfered slope 24 which extends from the respective neighboring lateral wall 18 at an obtuse angle, for example 150. During an additional stress on the cover 8 against the abutment flanges 22, their slopes 24 cause a lateral spacing of the bearing steps 10, directed towards the outside, so that the pivot pins 14 are then disengaged from the openings of pivot 16, thereby removing the cover from the part
