Abstract
A closure assembly for a medical device including an administering device such as, but not limited to, a prefilled syringe, includes a housing having an access opening, a stop member disposed therein and an end cap. A tip cap, attachable in a flow restricting relation to the medical device is disposed within the housing and is removably connected to a base, wherein the stop member restricts removal of the flow restrictor from the housing through the access opening. The base is disposed in a captured orientation between the stop member and the end cap. The flow restrictor is disconnected from the base when a predetermined force is applied to flow restrictor, as the housing is rotationally attached to the medical device. The flow restrictor remains attached in flow restricting relation to the medical device while being disconnected from the base until the housing is detached from the medical device.
