A closure assembly structured for use with a female luer connector operative to indicate an attempted tampering or access thereto. A flow restrictor is movably and removably disposed within a housing and includes a male connector, such as a male luer connector, inserted in flow restricting engagement within an interior port of the female luer connector. An indicator member is removably connected within the housing and a drive assembly associated with both the flow restrictor and the housing is operable to dispose the male connector in flow restricting engagement within the female connector. Attempted removal of the closure assembly from the female connector will detach an indicator member from the housing and visually expose it, thereby indicating attempted access.

1. A closure assembly for a female connector structured to indicate attempted access to the female connector, said closure assembly comprising: a housing including an at least partially hollow interior and a closed end portion,a flow restrictor movably disposed within said housing and structured for connection to the female connector,said flow restrictor including a male plug member dimensioned and configured for insertion in flow restricting engagement within an interior port of the female connector,said flow restrictor further including a casing having an interior surface disposed in surrounding, spaced relation to said plug member;said interior surface of said casing cooperatively structured with an exterior of the female connector to establish a connection therebetween,said male plug member disposed within and extending outwardly from said casing in a centrally disposed coaxial relation to said interior surface, andsaid flow restrictor and housing cooperatively structured for concurrent rotational and axial movement of said male plug member into said inserted, flow restricting engagement with the female connector. 2. A closure assembly as recited in claim 1 further comprising an indicator member fixedly and removably connected within said housing and detachable therefrom upon removal of said housing from said flow restrictor. 3. A closure assembly as recited in claim 2 wherein said indicator member comprises an annular configuration disposed in surrounding relation to at least a portion of said flow restrictor on an interior of said housing. 4. A closure assembly as recited in claim 3 further comprising at least one frangible connector disposed in removable, interconnecting relation between an interior surface of said housing and an exterior surface of said indicator member. 5. A closure assembly as recited in claim 2 wherein said indicator member is retained in surrounding relation to an exterior of said flow restrictor upon removal of said housing from said flow restrictor and connection of said flow restrictor to the female connector. 6. A closure assembly as recited in claim 1 further comprising a drive assembly disposed on both said closed end portion and said flow restrictor and cooperatively structured therewith to facilitate rotation of said flow restrictor in only one direction upon predetermined rotation of said housing relative to the female connector. 7. A closure assembly as recited in claim 1 wherein said casing includes a threaded portion disposed on said interior surface, said threaded portion disposed and configured to define a threaded engagement of said flow restrictor with an exterior of the female connector upon rotation of said male plug member relative to the female connector. 8. A closure assembly as recited in claim 1 wherein said male plug member comprises an elongated configuration having a tapered, closed exterior surface terminating in a closed outer end. 9. A closure assembly as recited in claim 8 wherein said tapered configuration and length of said male plug member is sufficient to define a fluid seal within the interior port of the female connector when disposed in said inserted, flow restricting engagement within the interior port of the female connector. 10. A closure assembly for a female luer connector structured to indicate attempted access to the female connector, said closure assembly comprising: a housing including an at least partially hollow interior and a closed end portion and an open end disposed in communicating relation with said hollow interior,an indicator member fixedly and removably connected within said housing and detachable therefrom,a flow restrictor movably retained within said housing between said closed end portion and said indicator member,said flow restrictor including a male luer connector comprising a plug, said plug disposed and structured for inserted, flow restricting engagement within an interior port of the female luer connector,said flow restrictor further including a casing having an interior surface disposed in surrounding, spaced relation to said plug;said interior surface of said casing cooperatively structured with an exterior of the female connector to establish a connection therebetween,said plug disposed within and extending outwardly from said casing in a centrally disposed coaxial relation to said interior surface,a drive assembly disposed on both said closed end portion and said flow restrictor and cooperatively structured therewith to facilitate rotation of said flow restrictor in only one direction upon a predetermined rotation of said housing relative to the female connector, andsaid housing and said flow restrictor cooperatively structured for concurrent rotational and axial movement of said plug into said inserted flow restricting engagement within the interior port of the female connector, upon said predetermined rotation of said housing. 11. A closure assembly as recited in claim 10 wherein said drive assembly comprises a first drive segment mounted on said closed end portion and a second drive segment mounted on a portion of said flow restrictor disposed in confronting relation with said closed end portion. 12. A closure assembly as recited in claim 11 wherein said first and second drive segments are cooperatively structured to rotate said flow restrictor and said plug in only one direction upon said rotation of said housing. 13. A closure assembly as recited in claim 10 wherein said casing includes a threaded portion disposed on said interior surface thereof, said threaded portion disposed and configured to define a threaded engagement of the flow restrictor with the female connector upon said concurrent rotation and axial movement of said plug. 14. A closure assembly as recited in claim 10 further comprising at least one frangible connector disposed in removable, interconnecting relation between an interior surface of said housing and an exterior surface of said indicator member. 15. A closure assembly as recited in claim 14 wherein said indicator member is detachable from said housing and retained in surrounding relation to said flow restrictor upon a predetermined axial force being applied to said housing. 16. A closure assembly as recited in claim 15 wherein said predetermined axial force is sufficient to remove said housing from an interconnecting relation to said female connector. 17. A closure assembly as recited in claim 10 wherein said flow restrictor includes a casing having an exterior structure at least partially defined by a plurality of curved segments and a plurality of flat segments, each of said flat segments disposed between and adjacent to two of said plurality of curved segments. 18. A closure assembly structured to indicate attempted access, said closure assembly comprising: a female connector associated with an apparatus for administering intravenous fluids to a patient and including an interior port,a housing including an at least partially hollow interior and a closed end portion,a flow restrictor movably disposed within said housing and structured for connection to said female connector,said flow restrictor including a male plug member dimensioned and configured for insertion in flow restricting engagement within said interior port of said female connector,said flow restrictor further including a casing having an interior surface disposed in surrounding, spaced relation to said plug member;said interior surface cooperatively structured with an exterior of the female connector to establish a connection therebetween,said flow restrictor and housing cooperatively structured for concurrent rotational and axial movement of said male plug into said inserted, flow restricting engagement with said female connector.
