But, the compiled file is not important for the builder, so, when the builder ends, I want to delete the object files generated by the compiler. I use de Delete() from SCons.Defaults.

Safe to assume you have a custom builder for your tool?
You could change:
env['SHOBJSUFFIX'] = '.o'

That's one way.
If you have a custom builder the action for the builder can be an array of strings so ['compile ${SOURCE}…','rm -rf ${TARGET}'] or something like that.
