the connector 7 side i e towards the longitudinal axis of the tension support part 56 the tension support part 56 provides the abutment portions 105 at opposing sides of each connector 7 received by the tension support part 56 accordingly the tension support part 56 abuts in circumferential direction against each side of the connector 7 which is covered by the tension support part 56 in other words the tension support part 56 is adapted to receive the connector 7 in a fitted manner additionally the abutment portion 105 provides abutment surfaces in longitudinal direction to further improve a positive locking in said direction fig9 shows a perspective side view of a cable sealing and retaining device 80 according to a further embodiment provided with two cable sealing devices 100 same reference signs relate to corresponding portions and parts described above the cable sealing and retaining device 80 comprises two cable sealing devices 100 each comprising a fixation part 112 which differs from the above described fixation part 102 by omission of the interstice 103 the interstice 103 is formed between longitudinal end sides of an adapter 71 which extends between the fixation parts 112 of the cable sealing devices 100 and a corresponding longitudinal end side of the fixation part 112 particularly the cable connection provided between the longitudinal end sides of the cable sealing devices 100 and radially supported by the tension support part 56 is covered by the adapter 71 having a longitudinal length smaller than a longitudinal distance formed between facing longitudinal end sides of the fixation parts 102 the adapter 71 provides a longitudinal length corresponding to a longitudinal distance between opposing inside surfaces of the key forming flanges provided.
