A device for use in a stapler for locking a member (1) displaceable along a bar (4) in an optional displacement position, said member carrying a catch for the object to be stapled, has a locking means (6) formed with a through hole through which the bar (4) extends and which is designed such that the locking means is nonrotatably connected to the bar but is tiltable therealong between a free position wherein the locking means (6) is freely displaceable along the bar (4), and a pinch position wherein the locking means (6) is pinched to the bar (4). The locking means (6) is disposed in a slot (5) in the displaceable member (1), two opposed wall surfaces (5a, 5b) of the slot forming on the one hand a carrier means adapted to carry along the locking means when the displaceable member (1) is displaced along the bar (4) and, on the other hand, an engagement means adapted to engage the locking means in order to tilt the latter between its free position and its pinch position when the bar and hence the locking means are turned, the locking means (6) in its pinch position locking the displaceable member (1) to the bar (4) in cooperation with the carrier means. |
