A coupling (10) is provided to create a connection between two tubes (12) and includes a first coupling body (14) having an externally threaded end (26), and a second coupling body (16) has an internally threaded end (32) operably engaged with the externally threaded end (28). A first deformable ring (18) is located in the first coupling body (14). A second deformable ring (20) is located in the second coupling body (16). A sleeve (22) is located in the first and second coupling bodies (14,16) extending between the first and second deformable rings (18,20). The coupling (10) has a free condition wherein tubes (12) can be inserted into the coupling (10), and a connecting condition wherein the first and second deformable rings (18,20) are engaged with the sleeve (22) and the first and second coupling bodies (14,16) to be deformed into engagement with any tubes (12) that have been inserted into the coupling (10).
