US Patent 6848388 Quick release fastener for flags and flag staffs

An apparatus for quickly installing a flag on and removing a flag from a golf hole flag staff is disclosed. A flag staff attachment having laterally displaceable retaining clips is threaded onto the top of a golf hole flag staff, and a retainer cap is installed through the aperture at the top of the sleeve of a golf hole flag. Laterally displaceable retaining clips on the retaining cap engage the flag sleeve's aperture, thereby securing the retaining cap to the flag. An engagement member on the retaining cap displaces the retaining clips of the flag staff attachment, thereby allowing the engagement member to pass therebetween, thereby securing the flag to the staff.
