A suction cup for holding signs has a cup portion and a neck portion to which a clamp member is connected. The clamp member has a first leg attached to the neck portion and a second leg adjacent a top surface of the neck portion. The second leg of the clamp member is movable away from the top surface of the neck portion to allow an object, such as a sign, to be inserted and held between the top surface of the neck portion and the clamp member. The second leg is biased against the neck portion such that the top of the relatively soft neck portion is used as a gripping surface to hold the sign. The top surface of the neck portion and the second leg of the clamp may have various surface configurations such as notches or grooves to enhance the gripping force therebetween.
