The device (1) has a set of fixing units (10, 10') that is arranged for fixing an object (2) i.e. guard rail, on a prefabricated wall (3). A placing unit (11) is arranged to place the set of fixing units to fix the object on the prefabricated wall at a given distance of a head (30) of the wall. A casing (100) is arranged along with a screw (102), and the head is equipped with an imprint for reception of an actuation tool. The head is screwed inside the casing. The head is intended to rest in a mold for manufacturing of the prefabricated wall. An independent claim is also included for a system for assembly of a guard body on a prefabricated wall of a building.
