Abstract
A protective bellows formed by injection (blow) moulding has a large-diameter end with a fixing collar (28) for sealingly embracing an externally tri-lobed surface of a housing of an articulation joint for a motor vehicle transmission. The fixing collar (28) comprises a circumferential outer surface 29 and an inner surface (30). The inner surface (30) is made up of part-circumferentially curved surface portions (30A, 30B, 30C) for engaging the three lobes of the housing, and three equi-angularly spaced inwardly curved integral surface portions (32A, 32B, 32C) which are shaped to engage the spaces or grooves between the three lobes on the housing. The resilient material between the outer surface (29) and each inwardly curved surface portion (32A, 32B, 32C) is formed with several slots (34) arranged with their depths directed in a radial direction. The slots (34) aid the de-moulding process.
