<p>The lance has a diffusion head (30) through which a water jet exits, and a body (32) with a connecting unit (34) to a fluid supply pipe (36). An extension (46) is interposed between the body and the diffusion head, where the extension includes a bent portion (50) near an end (48) connected to the diffusion head, and a movable support (60) supporting the extension. A ball joint type connection (62) between the movable support and the extension permits pivotal movement of the extension relative to the movable support.</p> |
