A safety handle device adapted to be installed on a wall, said safety handle device being characterized by: a handle tube unit adapted to be disposed at a spacing from the wall and formed with a tube channel that extends along an axis of said handle tube unit, and that has two openings opposite along the axis of said handle tube unit, said handle tube unit having a plurality of mounting holes that are in communication with said tube channel; a plurality of joint members (3, 4) corresponding respectively in position to said mounting holes and detachably disposed in said tube channel of said handle tube unit, each joint member (3, 4) having an engaging bore (311, 411) that is in alignment and communication with the respective mounting hole; and a plurality of support tube units joined to said joint members (3, 4) respectively and coupled detachably to said handle tube unit, each support tube unit including a support tube subunit, a fastening member, a securing seat, and a securing member, said support tube subunit being in aligned with a respective mounting hole and detachably coupled to an outer surface of said handle tube unit, said fastening member passing from an interior of said support tube subunit through the respective mounting hole of said handle tube unit and engaged detachably with said engaging bore of the respective joint member (3, 4), said securing seat being adapted to be fixed to the wall and connected to said support tube subunit; wherein, for each support tube unit, said support tube subunit has a pedestal connected to said securing seat, a support tube extending from said pedestral to said handle tube unit; wherein for each support tube unit, said pedestal of said support tube subunit has a base wall and a surrounding wall surrounding said base wall and extending from said base wall in a direction away from said support tube, said base wall and said surrounding wall cooperatively forming an accommodating groove that accommodates said securing seat; characterized in that: said securing member is extending detachably into said support tube subunit and is connected detachably to said securing seat; for each support tube unit, an insert piece is disposed in the interior of and welded to said support tube, said fastening member passing through said insert piece; and for each support tube unit, said support tube is welded to said pedestal at an intersection that is located in said accommodating groove. a handle tube unit adapted to be disposed at a spacing from the wall and formed with a tube channel that extends along an axis of said handle tube unit, and that has two openings opposite along the axis of said handle tube unit, said handle tube unit having a plurality of mounting holes that are in communication with said tube channel;
