A refill head, and oral care implement incorporating the same, wherein the refill head can be uncoupled from a stem of a handle by withdrawing the refill head from the stem of a handle along the longitudinal axis of the oral care implement, which results in locking members on the refill head disengaging from an engagement rib on the stem. The locking members and engagement rib may be aligned with or angled relative to the longitudinal axis of the oral care implement. A portion of the stem may be visible through a portion of the refill head to reinforce the proper connection between the refill head and the handle.
