PURPOSE: A penetration sleeve fixing pin is provided to enable simple installation of a penetration sleeve and prevent the infiltration of concrete through a gap between the penetration sleeve and a form. CONSTITUTION: A penetration sleeve fixing pin comprises a cylindrical body(21), a holding protrusion moving groove(22), a form holding protrusion(23), a guide unit(24), and a head(25). The cylindrical body has a diameter which is equal to or less than the inner diameter of a fixing unit insertion part of a form fixing unit which is formed on the bottom of the penetration sleeve. The holding protrusion moving groove is formed by longitudinally cutting the center part of the body. The form holding protrusion is formed on both sides of the holding protrusion moving groove to be larger than the fixing unit insertion part at the top and tapered to the diameter of the body. The guide unit is formed on the bottom of the protrusion to be tapered. The head is formed on the top of the body and has a diameter greater than the inside diameter of the fixing unit insertion part.
