ABSTRACT:
A device for releasably locking, in a tubular first member (1), a second member (2) which is displaceable in the first member, has a slide (6) mounted on the first member. A driver pin (7) on the second member <2) extends through a slot (4) in the first member and through a hole in the slide to entrain the slide in the displacement of the second member. A spring (9) urges an operazing lever (8) rotatably mounted on the driver pin (7), towards the slide (6). The slide has cam means (10) cooperating in such a manner with the operating lever (8) that this lever, when being rotated from a free position to a locking position, is urged out from the slide against the action of the spring (9), such that the spring urges the driver pin (7) outwardly so as to resiliently urge the second member (2) against the first member (1) which is thus clamped between the slide (6) and the second member (2), whereby to lock the latter in its position of displacement.
