Zaklopac (m)
non-return valve of the blowpipe
Usually a piece of leather fastened (inside the bag) to the blowpipe stock; Only bagpipes in Zelovo and Poljica (Dalmatia) have a valve on the blowpipe itself; Bagpipes of Brest and Ćićarija (a mountainous plateau in the northern and northeastern part of the Istria peninsula) have no valve whatsoever (during playing the piper has to close the blowpipe with his tongue to prevent air from escaping); NB: ➺ homonyms.
