A device and method for plugging a tube that includes setting a tapered plug in a tube with a compression ring that circumscribes the plug. The ring radially expands when axially compressed and wedges the plug in the tube. An anchoring assembly fits over the tapered end of the plug and is coupled to the plug while being pushed against the compressed ring. When coupled to the plug, the anchoring assembly maintains the ring in a compressed state. The anchoring assembly can be made up of legs that fasten to the tapered end of the plug and have shoulders attached on a free end that are positioned against a lateral side of the compressed ring.

The present invention relates to a connector device suitable for connection between a heat exchange tube with a flat configuration and at least one conduit which can be a liquid coolant feed conduit, a liquid coolant return conduit, or both. The connector device is particularly suitable for heat exchange tubes for heat exchange with battery cells where the free spaces left by the cell cluster are filled with foam. Barrier means which are interposed between the outside of the connector and sealing means established in the attachment with the exchange tube are used in the connector. The barrier means prevent, or at least hinder, the entry of the foam used when manufacturing the battery while allowing the verification of the existence of leakages, for example, in quality control testing.
