The invention relates to a device for interrupting selectively a rotary translational movement, comprising a threaded elongated element ( 14; 114 ) and an element ( 112 ) having a female thread mating with the thread of the elongated element ( 14; 114 ), one of said elements ( 112, 14; 114 ) performing a translatory movement as far as at least a position defined by an end-of-travel stop ( 150 ) as a result of engagement with the other element, and said translating element being able to undergo momentary deformation upon reaching said at least one end-of-travel position ( 150 ) with the effect of being disengaged from the other element.
