A pad holder adapted for use with a coupling device which is operably connected to a rotatable drive shaft of a floor maintenance machine includes first and second pad holder members rotatably and detachably joined in coaxial relationship by lugs and cam-like ramps. An annular floor cleaning or polishing pad is held between the pad holder members and gripped for rotation by the drive shaft. Pull tabs are provided for moving the lugs away from engagement with the ramps to quickly disassemble the pad holder.
