Maybe you are looking for signal_handler_disconnect()  ? 
Followed by an undef ?

#!/usr/bin/perl
use warnings;
use strict;
use Glib qw/TRUE FALSE/;
use Gtk2 '-init';

sub callback{
 my ($button, $data) = @_;
 print "Hello again - $data was pressed\n";
}

sub delete_event{
 Gtk2->main_quit;
 return FALSE;
}

my $window = Gtk2::Window->new('toplevel');

$window->set_title("Hello Buttons!");
$window->signal_connect(delete_event => \&delete_event);
$window->set_border_width(10);

my $box1 = Gtk2::HBox->new(FALSE, 0);
$window->add($box1);

my $button1 = Gtk2::Button->new("Button 1");
$button1->signal_connect(clicked => \&callback, 'button 1');
$box1->pack_start($button1, TRUE, TRUE, 0);
$button1->show;

my $button2 = Gtk2::Button->new("Button 2");
my $sigbut2 = $button2->signal_connect(clicked => \&callback, 'button 2');
$box1->pack_start($button2, TRUE, TRUE, 0);
$button2->show;

$box1->show;

$button2->signal_handler_disconnect($sigbut2 ); 
undef $sigbut2;

$window->show;

Gtk2->main;
__END__
