An anchoring device will cooperate with a slotted aperture in a planked surface, such as a deck or boat dock, is disclosed. An example of the invention includes an internal tube that is telescopically mounted within a hollow cylindrical external tube. A support flange that is mounted to the bottom of the internal tube at one end and to a support flange at the other end extends through the bottom of the external tube. A spring is mounted between the bottom of the internal tube and the bottom of the external tube, so that the spring may be compressed by sliding the internal tube into the external tube. The sliding of the internal tube into the external tube causes the support flange to extend, so that the planked surface may be gripped between the support flange and the bottom of the external tube.
