The e-looseness of a plane graph ?$G$? is the minimum positive integer ?$k$? such that any edge coloring of ?$G$? with ?$k$? colors involves an e-loose face. In this paper we determine tight lower and upper bounds for the e-looseness of connected plane graphs. These bounds are expressed by linear polynomials of the number of faces</dc:description><dc:description xml:lang="sl">Lice povezavno pobarvanega ravninskega grafa se imenuje e-rahlo, če so njegove stranice pobarvane z najmanj tremi barvami; e-rahlost ravninskega grafa ?$G$? pa je najmanjše naravno število ?$k$?, pri katerem vsako barvanje povezav grafa ?$G$? s ?$k$? barvami vsebuje e-rahlo lice. V tem članku določimo tesno spodnjo in zgornjo mejo za e-rahlost povezanih ravninskih grafov.
