A sponge refill backplate for easy replacement on mop heads having mop clips, turn-lock assemblies or long slotted attachment members comprising opposed raised locking clips open only at their distal ends having locking slots with a wider channel below to receive a mop clip, the locking slot being of sufficient length so that mop clips on a sponge mop head may slide far enough into the locking clip to allow the outer side of the opposite locking clip to fall into place at its attachment without bending the backplate or sponge; and a pair of locking ramps located at the open distal end of each locking clip, angled inwardly toward the open end to assist in loading the refill and which acts as stop members for the mop clips or long slotted attachment members but which may be overridden by a predetermined force in the longitudinal direction of the mop head. This is an advantage over most current sponge refills which require wetting and/or bending the sponge and backplate to attach the refill to the mop head.
