Abstract
A cap for closing a tubular opening, especially the opening of an oil filler tube, which cap comprises a first part or cover part 12, which can be attached to the tubular opening by a bayonet lock, and a second part provided as an inside part 13, which is freely rotatable on the cover part 12 and is attached to the cover part 12 by a snap fastener 22. On the inside part 13 is a gasket 14 which seals the tubular opening. Sliding contact surfaces 20, 21 are provided between the inside part and the outer cap, so that no shearing forces act on the inside part or on the gasket when the tubular opening is closed or opened, thereby substantially facilitating the closing and opening of the tubular opening.
