ABSTRACT:
An improved razor head for attachment to a razor handle comprising a pair of inwardly directed fingers for engagement with a pivotable razor cartridge is provided with a single button for attachment of the razor head to the cartridge. The button is positioned for ease of operation by the thumb when the razor handle is grasped by the user and pressure on the button is effective to move the fingers linearly outwardly along a line parallel to the cartridge width dimension, or razor edge. The fingers are locked in the outward, or open, position after release of the pressure on the button and are returned to the inward or engaging position through contact of the cartridge with a cam follower on the razor head.
