A drill string guiding device (2) for holding elongate drill string components (3, 3', 3") during assembling or disassembling of a drill string (4) in a drilling operation, the drill string guiding device (2) comprising a frame (6) with an opening (7) through which the drill string (4) is arranged to protrude during operation, the drill string (4) extending in an axial direction (A 1 ). A holding device (8) is arranged, and a positioning device (13) is arranged on the frame (6) for positioning the holding device (8) between an inactive position and an active gripping positon in which it is arranged to hold the drill string component (3') as an adjacent drill string component (3) is being connected thereto or removed therefrom. The holding device (8) comprises a guiding support (11) comprising upper, lower and side portions arranged to partially enclose and fix a section of said first drill string component (3') and a guiding support (11) with at least one guide surface (12a,12b) for aligning said drill string component (3').
