The invention relates to a load disconnection lock having a locking device (35, 36, 37) which is secured against unlocking by means of a safety device (40, 41) as long as the tensile load is not less than a predefined minimum value, and which unlocks automatically as soon as the tensile load is less than the predefined minimum value. In accordance with the invention, a second safety device is provided for the locking device (35, 36, 37) and has a fluid-filled housing (10) in which a piston (20) is guided, which piston (20) has a tensile load applied to it and has a hole (22) as a flow channel for the fluid, such that the fluid can be exchanged between the two housing subareas (15, 16) on both sides of the piston (20) with the piston (20) being connected to an activation slide (25) which releases the locking device (35, 36, 37) as soon as the piston (20) has moved through a predetermined distance. |
