Abstract
A refill head, and oral care implement incorporating the same, wherein the refill head comprises a tubular sleeve having a cavity for slidably receiving a stem of a handle of the oral care implement. An aperture in the tubular sleeve defines a latch having a locking lug that operably mates with a locking lug of the stem to axially retain the refill head to the handle. A resilient material seals the aperture to provide increased rigidity to the latch.
