PROBLEM TO BE SOLVED: To provide a hook obstructing visual observation and hiding worsening of appearance even when exposure of a pin or dents worsen the appearance after installation. SOLUTION: The hook 1 is installed on a concrete wall 12 or the like. An annular gap 31 is formed between the inner peripheral surface of an elliptical fitting recess 7 in a mounting base 3 and the outer peripheral surface of a head portion 10 of a plug-in pin body 5. An annular plug-in portion 30B of a cover body 30 is plugged into the gap to cover the front face of the head portion 10 of the pin body 5 with a front face covering portion 30A of the cover body 30 so that exposure of the pin 11 or dents caused on the front face of the head portion 10 during installation of the hook 1 are obstructed from visual observation to hide worsening of the appearance.
