An item holder, mountable by suction on a mounting surface, including a deformable body having a convex outer surface that is substantially free of protrusions, a concave inner surface, and an edge extending around the outer and the inner surfaces. The deformable body is shaped to form in the body an elongate void extending through the deformable body, between the concave inner surface and the convex outer surface, in a direction that is generally parallel to the mounting surface during use of the holder. The elongate void formed by the deformable body terminates at opposing openings including of a first opening opposite a second opening. The body also defines a suction portion needed for creating the suction between the body and the mounting surface. The holder also includes a link component extending into the first opening, through the elongate void, and out of the second opening.
