Claim:
Connector fitting ( 1 ) for fixing a longitudinal body to an opening in a wall, wherein the connector fitting ( 1 ) comprises: a chuck ( 2 ), which penetrates the opening in a position of use and is provided with slits that extend generally in an axial direction, said chuck comprising a thread located on a section, the section adapted to be arranged and remain in front of the wall opening, wherein the chuck is capable of radially expanding outwards in an insertion direction behind the wall opening into a clamping region containing the slits, and can be tightened on an outer side or in front of the opening of the wall by the thread; and a matching tensioning nut ( 3 ), such that the clamping region can be directly or indirectly, at least partially, withdrawn into the opening and thus braced against the longitudinal body, wherein the tensioning nut ( 3 ) comprises: a radially inwardly extending abutment ( 4 a , 4 b ) extending in the axial direction and the chuck ( 2 ) comprises a counter-abutment ( 5 a , 5 b , 5 c , 5 d ) adjacent to the thread section and the counter-abutment ( 5 a , 5 b , 5 c , 5 d ) exerts pressure on the abutment ( 4 a , 4 b ) in a released position of the chuck ( 2 ); and a sleeve-like extension ( 3 a ) located adjacent the thread section and extending in the axial direction, within which the radially inwardly extending abutment ( 4 a , 4 b ) is arranged.
