Abstract

A closure assembly for a medical device such as a syringe comprises a housing having an open end and a hollow interior. A tip cap is removably disposed within the housing and includes a cover connected to the open end by a snap-fit connection. An indicator ring includes an access opening and is removably connected to the cover in interruptive, removable restricting relation to said tip cap. The access opening is dimensioned to facilitate passage of the syringe therethrough into attachment with the tip cap, with the tip cap disposed into disconnecting engagement with said indicator ring concurrent to removal of said tip cap and attached syringe through said open end. Upon removal of the tip cap and attached syringe through the open end of the housing, the indicator ring will be disposed in a surrounding captured disposition on the syringe, thereby providing a clear indication of tampering or use.
