PCT No. PCT/SE84/00041 Sec. 371 Date Sep. 18, 1984 Sec. 102(e) Date Sep. 18, 1984 PCT Filed Feb. 8, 1984 PCT Pub. No. WO84/03132 PCT Pub. Date Aug. 16, 1984.A rubber bellows (1) for sealing between an air intake on a spring-balanced, tilting truck cab and a connecting pipe (5) securely mounted on the chassis. The connecting pipe is provided at one end with a bead (7) and the bellows and the corresponding end with an interior lip (6), which when the bellows is connected to the pipe is forced over the bead and in its coupled position is inclined towards the bead, so that the force necessary to pull off the bellows is substantially greater than the force necessary for connecting the bellows.
