Abstract:
Process for connecting a pipe (2, 31) in the region of its pipe end to a pipe coupling (1), comprising at least one support sleeve (3) with an engagement means (5, 65, 67, 124), wherein the pipe (2, 31) and the support sleeve (3) are first pushed into one another, the pipe (2, 31) then being pressure deformed, thereby bringing about a form-fitting connection with the engagement means (5, 65, 67, 125) and bringing about a sealing relationship with sealing surfaces (7, 66, 68, 122), mutually adjoining each other in axial direction, characterized in that an axial force, bearing on the sealing surfaces (7, 66, 68, 122) is applied to the pipe (2, 31) by a pressure sleeve acted on by a spring means (20, 52) radially deformed by said pressure sleeve and deriving support from the pipe coupling (1), said spring means creating said axial force due to said radial deformation.
