Abstract

A coupling connection for corrugated pipes includes a coupling element, a support ring which is attachable in a positive fit against an inner wall face of the corrugated pipe, a first annular element which is axially fixable on a circumferential face of the corrugated pipe, a portion of the corrugated pipe being enclosed between the support ring and the first annular element and being fixable axially immovably, and an annular sealing chamber, enclosed circumferentially in a transition region between the support ring and the corrugated pipe, receiving a sealing element, on which a deformation force acts in a functional position which is fixable using a fixing element, including a second annular element, which circumferentially encloses the coupling element and is circumferentially attachable and movable in translation with respect thereto, the first annular element and the second annular element being arranged mutually coaxially.
