A cover assembly for restricting access to an access opening includes a cover member and a flexible member. The cover member includes a central covering portion surrounded by an outer peripheral collar portion defining a passage, and a tab affixed to the collar portion, with the tab including at least one tab aperture. The flexible member extends through the passage and has a first end extending outward of the passage and including at least one flexible member aperture, and a second end secured to the collar portion. When the first end of the flexible member is pulled, the collar portion of the cover member is constricted, and one of the at least one flexible member apertures is aligned with one of the at least one tab apertures to receive a locking member therethrough, thereby securing the collar portion in a constricted condition. |
