Patent ID: 6869112

Claim:
A device for locking two elongate elements, a first of which slides in a second telescopically, the device comprising means ( 12 ) for locking the first element ( 2 ) in a first longitudinal direction with respect to the second element ( 4 ), which means comprise a locking washer ( 13 ) arranged around the first element and a circumferential part of which is placed between two longitudinally opposed supports of said second element and an elastic return member ( 18 ) placed between said second element and said washer and acting in said longitudinal direction on the washer at a point distant from said supports so as to bring the washer into an extreme inclined position with respect to the first element, in which position two opposed parts of this washer are in contact with the first element so as to lock the first element ( 2 ) with respect to the second element ( 4 ) in said longitudinal direction, and a tilting member ( 5 ) articulated to said second element, a spacing member ( 20 ) placed between the washer and the tilting member and an operating member ( 32 ) allowing action on the tilting member so that action on this operating member causes the tilting member to tilt, which tilting member, via the spacing member acts on the washer in such a way as to move it away from its aforementioned extreme position against the action of said return means, reducing its inclination, so as to release the first element with respect to the second element.
