Claims

1. A fitting (1) for coupling to at least one pipe (2), comprising:

- a sleeve end (3, 10) for receiving the pipe (2);

- at least one sealing member (4, 9) to provide a seal to the pipe (2) received in said sleeve end (3, 10);

- a pressure member (5) for applying a pressure to the sleeve end (3, 10) and to the pipe (2);

- gripper teeth (6) provided on the pressure member (5) and arranged to act on the pipe (2); and

- actuation means (7, 12) that are tuneable from outside the sleeve end (3, 10) for arranging that a pressure is applied to the pressure member (5),

wherein in use the pressure member (5) is subject to a pressure prevailing at the inside of the pipe (2) characterized in that the sleeve end (3, 10) is provided with an aperture (8) providing a fluid and/or gas connection from the inside of the pipe (2) towards a radially outward circumferential surface (5') of the pressure member (5).
  2. A fitting (1) according to claim 1, characterized in that the at least one sealing member (4) is positioned between at least the pressure member (5) and the pipe (2) .
  3. A fitting (1) according to claim 1 or 2, characterized in that the at least one sealing member (4) is further positioned between the pressure member (5) and the sleeve end (3, 10).
  4. A fitting (1) according to any one of claims 1 - 3, characterized in that it comprises a second sealing member (9) between a sleeve (10) and a pressurizing organ (3) forming part of said sleeve end (3, 10).
  5. A fitting (1) according to any one of claims 1 - 3, characterized in that the at least one sealing member (4) is connected to and/or follows at least part of an inner periphery of the sleeve end (3, 10).
  6. A fitting (1) according to any one of claims 1 - 5, characterized in that there are separate sealing members positioned between the pressure member (5) and the sleeve end (3, 10), respectively between the pressure member (5) and the pipe (2).
  7. A fitting (1) according to any one of the previous claims 1 - 6, wherein the sleeve end (3, 10) and the pressure member (5) have adjoining slanting contacting surfaces (11', 11'') to arrange that a force applied to the pressure member (5) with the actuation means (7, 12) in parallel with a longitudinal body axis of the sleeve end (3, 10), acts on the pressure member (5) with a component perpendicular to said longitudinal body axis on the pipe (2) received in said sleeve end (3, 10).
  8. A fitting (1) according to any one of claims 1 - 7, characterized in that the actuation means (7, 12) are hydraulically, pneumatically and/or mechanically tuneable.
  9. A fitting (1) according to claim 8, characterized in that the actuation means are pneumatically tuneable by arranging that a bellow (12) is arranged to press towards the pressure member (5), and valve means (13) are applied at a circumferentially outwards position of the sleeve end (3, 10) for pressurizing said bellow (12).
  10. A fitting (1) according to claim 8, characterized in that the actuation means are mechanically tuneable by tuning means embodied with a bolt and nut (7), a screw connection, a rack and pinion or a spindle drive.
