The device includes a window frame which has a head having a first and a second side, the first and second sides defining respectively a first and a second slot. A sill has a first and a second extremity, the first and second extremities defining respectively a first and a second channel. A first jamb extends between the first side of the head and the first extremity of the sill and a second jamb extends between the second side of the head and the second extremity of the sill. A first tie adapter has a first and a second end, the first end defining a tenon which cooperates with the first slot, the second end defining a tab which cooperates with the first channel. A second tie adapter has a first and a second edge, the first edge defining a further tenon which cooperates with the second slot.
