Abstract: A fitting for coupling to a pipe includes a sleeve for receiving the pipe and a sealing member to provide a seal between the sleeve and the pipe. A pressure ring acts on a pressure member through adjoining slanting contacting surfaces of the pressure ring and pressure member, respectively. The sealing member is configured to be displaced from the slanting contact surfaces to preserve the life of the seal.

Abstract: Coupling device (1) for a pipe (2), including a sleeve (13) for receiving the pipe (2) and at least one sealing member (5) to provide a seal between the sleeve (13) and the pipe (2), a pressure member (6) for applying a pressure to the sleeve (13) and to the pipe (2), and a grip element (4) extending along at least a part of the perimeter of the pipe (2), wherein the grip element (4) is provided with dents (9) pressed out of the plane of the grip element (4) adjacent to slit like openings (8) punched out of the grip element (4), wherein edges (8?) of the slit like openings (8) are subjected to a peening operation.

Abstract: The invention relates to a coupling device for coupling with a tube, comprising at least one pressure element for exerting a clamping force on the tube, wherein the said at least one pressure element is one of a series of correspondingly embodied neighboring pressure elements, wherein each pressure element of said series comprises a first pressure element segment and a second pressure element segment, and wherein the first pressure element segment is placed proximally and the second pressure element segment distally with respect to the tube, and that of each pressure element the first pressure element segment is provided with a protrusion extending transversely to the longitudinal direction of the tube, and that said protrusion extends into a slot that is provided in a directly neighboring second pressure element segment that forms part of a neighboring pressure element.

Abstract: A coupling device for a tube includes a pressure element comprising first and second pressure element segments for exerting a clamping force on the tube. The pressure element includes surfaces that converge towards each other in a radial direction away from the tube and that are directly or indirectly disposed against support elements. The first pressure element segment is placed proximally and the second pressure element segment distally with respect to the tube. The first and the second pressure element segments are each provided with contact surfaces that abut and co-operate with each other at a predetermined incline in relation to the longitudinal axis of the tube such that during tension strain between the coupling and the tube, the first pressure element segment is caused to clamp the tube more tightly and the second pressure element segment endows an increased force on the support elements.
