FIELD: transport.
SUBSTANCE: tie-down hook, for example for aircraft, made capable to interact with tie-down grid (2) of platform contains devices (3) in the form of power cylinder containing bowl shaped devices (4) where piston-shaped devices (5) travel which are provided with rod extending outside bowl shaped devices and free end of which contains hook head (7) for engagement in the grid (2) which head is provided with pins (8, 13, 14) for retention in the latter moved by control devices (9) between retracted position and active position y means of control devices (9). The hook differs in that bowl shaped devices (4) of power cylinder contain at least two cylindrical parts (10, 11) being telescopic relive to each other and movable between retracted one inside the other position and active position when one part extends from another.
EFFECT: design improvement.
