A connector assembly ( 11 ) comprising a first hollow member which may be in the form of a first casing ( 13 ), and a second hollow member which may be in the form of a second casing ( 15 ). The first casing ( 13 ) has a first end ( 17 ) adapted to releasably retain a second end ( 21 ) of the second casing ( 15 ) therein. The connector assembly ( 11 ) further comprises a jacket ( 33 ) secured around a first outer portion adjacent the first end ( 17 ) of the first casing ( 13 ), and a second outer portion adjacent the second end ( 21 ) of the second casing ( 15 ). In use the jacket ( 33 ) bears against or is adjacent to a wall of a bore of a well. A sealed cavity ( 35 ) is defined between the jacket ( 33 ) and the outer portions of the casings ( 13, 15 ). When the connector ( 11 ) is assembled the cavity ( 33 ) is filled with a fluid and is in fluid communication with a vent ( 41 ). During disconnection of the first casing ( 13 ) from the second casing ( 15 ), the fluid in the cavity ( 35 ) is discharged from the cavity ( 35 ) through the vent ( 41 ) allowing the jacket ( 33 ) to move inwardly away from the bore wall to assist removal of the first casing ( 13 ) from the bore as it detaches from the second casing ( 15 ). |
