mop head attachment

also called head fitting

How a mop head fixes to its handle, which also determines whether the head is replaceable with a refill — a socket (the plastic/metal socket cotton mop), a clip (the plastic-clip attachment), a stay-flat band (a flat-mop band), or fixed/non-replaceable. A mop-only structural fact (a bristle or blade tool has no replaceable absorbent head). Concern facet (a nominal categorical descriptor, axis-eligible). Optional. NOTE: a bare replaceable head (a 'mop refill') is a deferred PART, not modelled here.
