The mouth is narrower and longer than the head which is stiff for forceably opening the mouth when it is inserted or removed from the secured position. The head has an undercut base for receiving the mouth wall when the head is locked in the opening. The overall arrangement is adapted to provide outward lateral flexing and inward lateral rebounding of the mouth wall at the undercut base of the head for removably securing the head in the opening.</p> |
