A closure assembly for a syringe or other medical administering device includes an outer sleeve having an access opening and a tip cap removably disposed therein. The tip cap includes a flow restrictor structured for removable, flow restricting connection to the syringe. An indicator member is removably connected within the outer sleeve, in interruptive relation to passage of the tip cap through the access opening. A retaining structure is fixedly connected to the flow restrictor and movable therewith relative to the indicator member. The retaining structure and flow restrictor are collectively structured for retaining engagement of the tip cap with the indicator member, as the tip and indicator member are concurrently removed from the outer sleeve and as the tip cap is disconnected from the flow restricting connection with the syringe.
