ABSTRACT:
The present invention relates to a coupling useful for repairing broken or otherwise damaged tubing. More particularly the invention includes a coupling body member which accepts the cut ends of the tubing being repaired, a pair of washer-seals one for each tubing end and a pair of locking rams which drive the washer seals into the coupling body member and into an expanded fit thereby providing a secure fitting. The rams are threadably received into the coupling body member and locked thereon against unintentional reverse rotation.
