A tubular connecting arrangement (10) comprises a first tubular (12) having a first shoulder (14) and first threads (16); a second tubular (22) having a second shoulder (24) and second threads (26); a seal (32) designed to be sealingly engageable to both the first shoulder (14) and the second shoulder (24); an insert (36) designed to be attachable to the second tubular (22), the insert (36) being configured to provide radial support to the second tubular (22) and including a flange that is compressed between the first shoulder (14) and the second shoulder (24) when the seal (32) is sealingly engaged with the first shoulder (14) and the second shoulder (24); and a sleeve (40) designed to be threadably engageable with both the first threads (16) and the second threads (26) in response to being rotated in a same direction relative to both the first tubular (12) and the second tubular (22) such that the first shoulder (14) and the second shoulder (24) are moved toward one another to compress the seal (32) therebetween without rotational movement of the first tubular (12) relative to the second tubular (22).
