摘要

A device ( 20 ) or restricting removal from the end of a tubular member ( 2 ) of a collar ( 4 ) or the like located on the tubular member ( 2 ) and a method using the device ( 20 ), the device ( 20 ) comprising an axially extending portion ( 22 ) for engagement in the end of the tubular member ( 2 ) and a radially outwardly extending portion ( 28 ) which in use is located outside the end of the tubular member ( 2 ) and which extends radially outwardly to a greater diameter than the internal diameter of the collar ( 4 ), thereby to restrict removal of the collar ( 4 ) from the end of the tubular member (2). In addition there is provided ( 20 ) for sealing the axially facing end of a tubular member ( 2 ), the device ( 20 ) comprising an axially extending portion ( 22 ) for engagement in the tubular member ( 2 ), a radially outwardly extending portion ( 28 ) which in use is located outside the tubular member ( 2 ) and a sealing means ( 48 ) for sealing between the radially outwardly extending portion ( 28 ) and the axially facing end ( 54 ) of the tubular member ( 2 ).
