Abstract
A one-piece plastic closure device for use in a filler hole, i.e. an oil filler cap or crankcase vent means, which seals the hole from the outside and can be applied with a fractional turn of the closure. The closure is adapted for use in a panel with an aperture having communicating lateral slots which telescopically accepts spring controlled retainer pads extending laterally from the closure body and that are moved to underlying relationship with the panel by rotation of the closure; the spring means acting on said retainer pads insuring continued sealing engagement of the closure with the panel.
