A safety device adapted for removable attachment to a selected one of the rungs of a ladder for securing the ladder to a structure against which it operatively positioned is disclosed. The device features a rigid hollow body which surrounds the selected rung, a pair of flexible straps secured to opposite end portions of the rigid body for being adjustably connected to a portion of the structure, and a flexible sheet or cover connected on one edge portion thereof to one side of the rigid body so that the sheet is disposed between the flexible strap connections. A free edge portion of the sheet opposite the one edge which is connected to the one side of the body is removably connectable to an opposite side of the body so that the sheet can confine the straps between itself and an underside of the body when the straps are not in use to secure the ladder to the structure.
