<p>The invention concerns a device for coupling two half-cylinders (4) having a so-called European profile, in which two bars (6) each have a first end suitable for being fixed to one of the half-cylinders and a second end hooked to an intermediate connection part (8) that extends longitudinally between the half-cylinders, via hooking elements borne respectively by said connection part and by said second end of the bar. A plurality of engagement positions are provided, a bar and/or the connection part having, longitudinally, a series of said hooking elements so as to allow the longitudinal adjustment of the coupling between said bar and said connection part. Advantageously, the hooking elements are in the shape of notched means having a longitudinal series of cutouts (62) and ribs (64).</p> |
