Special hyphen (teilamalül) used in Volapük typography, e.g. when syllabifying words (Vo⸗la⸗pük). Contrast that with using the common hyphen (yümamalül) applied in Volapük e.g. for writing double-barreled names (hiel ‚Jacques-Henri Bernardin de Saint-Pierre‘) or compound placenames (el ‚Saint-Georges-en-Auge‘).
For full explanation (in Volapük), see Gramat Volapüka/Malüls#s34 and vo:Teilamalül.
Best typographic approximation would probably be ⹀ 'DOUBLE HYPHEN' (U+2E40), but it lacks from many fonts, thus using 'DOUBLE OBLIQUE HYPHEN' (U+2E17) instead.
