Abstract: A removable obturation device is provided for transversely obstructing a passage delimited by a cylindrical side wall wherein it includes: a) a support and blocking element having a central block supporting a plurality of arms disposed perpendicularly in a radial position with respect to the longitudinal axis of the block and of the side wall, each arm having an extensible rod including a pad intended to be blocked against one the side wall, and b) at least one complementary obturation element extending in a radial transverse plane perpendicular to the longitudinal axis, at least partly in or opposite the space between the arms so as to prevent an individual from falling through the passage. The obstruction element is preferably removably fastened to the support and blocking element.
