A device for locking two elongated elements the first of which slides in the second telescopically, comprises members (12, 22) for locking the first element (2) longitudinally relative to the second element (4), a lock washer (13) arranged around the first element and whereof the circumferential part is placed between two longitudinally opposite supports of the second element and an elastic return member (18) placed between the second element and the washer and acting on the washer in a site at some distance from the supports so as to bring the lock washer in an extreme inclined position relative to the first element wherein the two opposite parts of the 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.

1. 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.2. The device as claimed in claim 1, further comprising a second means (22) for locking the first element in the other longitudinal direction with respect to the second element, which means comprise a second washer arranged around the first element and a circumferential part of which is placed between two second longitudinally opposed supports of said second element and a second elastic return member placed between said second element and said second washer and acting in said other longitudinal direction on the second washer at a point distant from said second supports so as to bring the second washer into an extreme inclined position with respect to the first element, in which position two opposed parts of this second washer are in contact with the first element so as to lock the first element with respect to the second element in said other longitudinal direction, and a second spacer member placed between the second washer and said tilting member so that the aforementioned action on this operating member acts also, via the second spacer member, on the second washer so as to move it away from its aforementioned extreme position against the action of said second return member, reducing its inclination, so as to release the first element with respect to the second element.3. The device as claimed in claim 2, characterized in that said first (12) and second (22) locking means are arranged on each side of said tilting member (5), said tilting member acting in opposite directions on said spacer members (20, 30).4. The device as claimed in claim 1, characterized in that said tilting member comprises a washer (5) which from a distance surrounds said first element and which is mounted in an articulated fashion on the second element, radially relative to the latter.5. The device as claimed in claim 1, characterized in that said washers (5, 13, 23) are arranged in internal annular housings (6, 14, 24) of the second element.6. The device as claimed in claim 1, characterized in that said spacer members comprise rods (20, 30) that can move longitudinally in passages of the second element.7. The device as claimed in claim 1, characterized in that said operating member comprises a rod (32) that can move longitudinally in a passage of the second element.8. The device as claimed in claim 1, characterized in that said operating member comprises an extension (34) of said tilting member (5), which extends through the wall of said second element.9. The device as claimed in claim 1, characterized in that the second element (4) comprises two assembled parts (4a, 4b) the mutual plane of contact of which extends along a longitudinal plane (33) passing through the axis of said elements, in that said return members, said spacer members and said operating member are arranged between said assembled parts of the second element, and in that said tilting member (5) is articulated to the second element about an axis (11) perpendicular to said plane of contact (4c).
