Expandable tubing connector for expandable tubing
First Claim
1. A tubing connector for joining the ends of two lengths of expandable tubing and permitting the joined lengths to be circumferentially expanded, the connector including circumferentially expandable tubular portions for mounting on the lengths of circumferentially expandable tubing and each circumferentially expandable tubular portion having a coupling part for joining with a coupling part of another tubular portion, a first coupling part of one tubular portion being of larger diameter to receive a second coupling part of another tubular portion, and the thickness of material at the connected coupling parts being greater than that of the remainder of the tubular portions, whereby following expansion of the connector and the tubing lengths the circumferentially expanded connector defines an upset from the tubing surface where said first and second coupling parts overlap.

Abstract
A tubing connector for joining the ends of two lengths of expandable tubing including two expandable tubular portions for mounting on the ends of the lengths of expandable tubing. Each portion includes a plurality of circumferentially spaced couplings for engaging corresponding couplings on the other portion. The engaging parts of the couplings are located on parts of the tubular portions which define an upset following expansion.
