<p>The pipe has external and internal connecting pipes (2, 3) including internal and external surfaces (2A, 3A) bent in a longitudinal direction. The surfaces of the pipes are provided with various chambers (RA, RB). A maximum internal diameter (D2) of the bent internal surface is smaller than the maximum external diameter (D3) of the bent external surface, so that an initial load is produced between the pipes during an insertion of the internal connecting piece into the external connecting piece or during with drawing the external connecting piece from the internal connecting piece. An independent claim is also included for a method for connecting two pipes.</p> |
