<p>The invention concerns a device for locking two elongated elements the first of which slides in the second telescopically, comprises means (12, 22) for locking in the longitudinal direction the first element (2) relative to the second element (4), which include a lock washer (13) arranged around the first element and whereof a circumferential portion is placed between two longitudinally opposite supports of said second element and an elastic return member (18) placed between said second element and said washer and acting on the washer in a point distant from said supports so as to bring the lock washer into an extreme inclined position relative to the first element wherein the two opposite parts of said washer are in contact with the first element so as to lock the first element (2) relative to the second element (4) in the longitudinal direction. The device further comprises a tilting member (5) articulated on said second element, a spacer member (104) placed between the lock washer and the tilting member and a control member (32) enabling to act on said tilting member, such that an action on said tilting member causes the tilting member to tilt which, via the spacer member, acts on the lock washer so as to space it apart from its said extreme position countering said elastic return means, by reducing its inclination, so as to release the first element relative to the second element.</p> |
