Abstract
A closure for removably sealing a port is provided. The closure includes a guide member receivable within an opening of a port and a sleeve member extending for a length of the guide member and defining with the guide member an annular channel, at least a portion of the port being received within the annular channel when the closure seals the port, the inner circumference of the sleeve member being sufficiently small to exert a retaining force around the portion of the port so received securing the closure onto the port. The closure includes a handle member having a reduced thickness portion, upon the application of a pulling force on the handle member the reduced thickness portion will stretch before the retaining force exerted by the closure on the port is overcome.
