Abstract

The present invention relates to a pipeline fixating device (14) comprising an expansion organ (16) which is at least partially insertable between an outer pipeline (12) and an inner pipeline (10) extending at least partially within the outer pipeline, the device comprising actuating means (24,24a, 24b) for expanding the expansion organ in a substantially radial direction with respect to the inner and outer pipeline for fixing the inner pipeline relative to the outer pipeline in at least an axial direction of the inner and outer pipeline.
