Victoria's opposition says it will get tougher on perpetrators of domestic violence, promising to impose jail sentences of up to 10 years for people who non-fatally strangle or choke a partner.

There is no specific criminal offence in Victoria of non-fatal strangulation, and on Sunday Opposition Leader Matthew Guy said the Coalition would, if elected, amend the Crimes Act to create one.

"For those offenders who believe that somehow they can choke or strangle their partner and get away with it, they'll get away with it no more," Mr Guy said.

"The government I lead will ensure that a 10-year maximum jail term will apply for those who strangle or choke their partner in a domestic violence setting."
