Mounting hardware for attaching a mop handle to a mop head including a mop head frame having a horizontal transverse cross bar, said hardware including a cylindrical barrel having a side outlet and having rotatably mounted therein a cylindrical spool with a groove formed in one side thereof, whereby when the groove and barrel outlet are angularly aligned, the cross bar may be inserted into said groove for rotation therein, and whereby when the spool is rotated out of alignment with the outlet, the barrel secures the cross bar in the groove, a manual lever for turning said spool in the barrel, a ferrule which may be fixed to the handle pivoted to said barrel on an axis at right angles to the spool, whereby the mop head can pivot universally relative to the handle, and means operable by the manual lever for selectively freeing or securing the ferrule against pivoting relative to the barrel, when the lever is in position to lock the cross bar in the spool groove.
