A pipe fitting comprising a housing ( 10:37:41 ) defining at ore rolled over end thereof an opening ( 36 ) through which it is intended a predetermined diameter pipe ( 28 ) is inserted, in use, with a clearance space between the pipe and the housing, The fitting has a grip-ring ( 19 ) for gripping the pipe ( 28 ) and a pipe support means ( 20:38 ) downstream of the grip-ring and ahead of sealing means ( 21 ). Downstream of the sealing means, are means ( 22:40 ) for limiting movement of the sealing means. The rolled over end of the housing effects engagement of the grip-ring with the housing and thus ensures electrical continuity between an inserted pipe and the housing.
