The end plate 6 is provided with a corresponding recess 19, which interacts with the lip 18 of the flange 17 so that when the flange 17 abuts the inside surface 14a of the end plate 6 the lip 18 enters the recess 19, and the connection pipe 9 cannot be rotated in relation to the end plate 6. The lip 18 can be shaped as a small portion of the flange 17, which is bent up from the flange surface to form a small portion extending from the surface of the flange (see 10 15 20 25 30 Fig. 10), directed towards the end plate 6, but is can also be shaped as a small pin, peg or similar that is mounted onto the periphery of the flange 17 and extending towards the end plate 6. lnstead of using the lip 18 for locking rotationally, an adhesive means can be used for achieving the same.The end plate 6 is provided with a corresponding recess 19, which interacts with the lip 18 of the flange 17 so that when the fl ange 17 abuts the inside surface 14a of the end plate 6 the lip 18 enters the recess 19, and the connection pipe 9 cannot be rotated in relation to the end plate 6.
