Liquefied petroleum gas is widely used in leisure time activities. Here, as liquefied petroleum gas is highly inflammable, it is important to have an indicator ( 19 ) that quickly determines whether there is leakage. The present invention relates to a new leak indicator ( 19 ) that, when an easily operated button ( 20 ) is pushed downwards into a cavity ( 8 ), indicates whether or not there is leakage. The space confined in the cavity ( 8 ) is completely closed off when the appertaining liquefied petroleum gas system is in normal operation mode.
