Abstract: A water-tight, rigid plastic, domed, sphero-cylindrical protective cap is configured to be removably fitted over the convex head of a steel tent stake. The protective cap defines a sphero-cylindrical interior compartment that has a substantially flat circular base with an axial aperture. The protective cap is bilaterally hinged so that the interior compartment can be opened and the axial aperture bifurcated so as to accept the stake head for insertion through the base and enclosure within the interior compartment when the cap is closed. The bilaterally hinged structure of the cap enables it to be easily attached and removed from the tent stake, so that it can be taken off and replaced when the tent is being moved. This avoids a major problem of non-removable stake caps, which become deformed when the stakes are pulled up and hammered back into the ground.
