<p>The invention relates to a lock screw comprising: a push element (3) which is intended to be mounted such that it can move between an inoperative position and an operating position in an axial hole (10) which is defined in the rear area of the screw; an end piece (4) which is used to retain the push element (3) inside the axial hole (10) of the screw; a coil spring (5) which acts on the push element (3) and which moves same into the inoperative position; complementary means which are used to guide the push element (3) through the axial hole (10) and to retain same in the operative position; and a flat spring (6) which is mounted transversely on the push element (3). The ends of the aforementioned flat spring are housed in such a way as to be able to move in transverse recesses (18) which are disposed in the threaded rod (1) and, moreover, said ends access the inside of the axial hole (10).</p> |
