The curve (26) has a tightening screw (28) which can increase or decrease the distance between its sides (36,38), thereby causing the retention and arrest component (24) to pivot either downwards or upwards, and at the same time to clamp completely or partially free the hatch. The hatch is pressed inwards in a loosely retained position by being pushed against slide surfaces (34) on the gripping part (32) of the retention and arrest component (24), causing the latter to be pressed downwards to snap-engage over the exterior of the hatch. Accordingly, the hatch is pressed inwards to tight location against the housing by tightening the screw (28). |
