spojnica

1. Croat. (in writing) hyphen
   Reč „crno-beli“ piše se sa spojnicom. — The word "crno-beli" is written with a hyphen.
2. (technical) connector; coupling
   Kupio sam novu spojnicu za baštensko crevo. — I bought a new connector for the garden hose.

In the sense "hyphen", spojnica is the Croatian term; in Serbia: crtica (and the dash is crta), and spojnica in this sense is rare.
