Static Template Page

Instead of showing my static page.
Wordpress show me the latest posts.

this is my : “pagedecontenu.php” code source

<?php
/*
Template Name: Page-de-contenu
*/
?>

<?php

get_header();
if (have_posts()) : while (have_posts()) : the_post();
?>
<div id="content-page">
<h1><?php the_title();?></h1>

<?php the_content(); ?>

</div>
<?
endwhile;
endif;

get_footer();
?>

The template is executed.
But, I think that there isn’t the static page id in the query. So wordpress show posts… I try to put a $post->ID on the query but that is’t work.

Thanks, i’m blocked …
