Insert quote into table problem

I'm trying to insert a row in a table, with a field that contains a quote.
Sql looks like this:
insert into pctable('1011 KN','1',' 8','10','Amsterdam ','Plein '40-'45'); I get an error ORA 01756: quoted string not properly terminated. How can I get the field with 'Plein '40-'45 into the table?

Greetz,
