A hook selection device for a shed-forming device for a weaving machine, in particular for a jacquard machine, has a number of hooks (3), (4) that can be moved up and down by a lifting means (1), (2). For each hook, there is a selection element with which the hook can be selected for being held by a holding element (5), (6) at a selection height. A resetting device (7) exerts a downward directed resetting force on the hook (3), (4), only during the movement on a path of the hook. The resetting device (7) is provided to transmit the resetting force to a contact part (8) of the hook that is lower than the top hook extremity, while each resetting device comprises a pressure device (10), which can be moved upward by a hook (3), (4) against a downward directed spring pressure. With such a hook selection device it is also possible to exert an effective resetting force on non-form-retaining hooks, while the hooks can be easily removable, and while the additional power that is consumed by the device is kept to a minimum.
