The channel has an upstream end communicating with the gun. The pipe has a rear groove (9) on which a front radial projection (10) of the gun is supported so as to prevent the expulsion of the gun from the interior of the pipe. The gun is formed by transparent or translucent material that presents rigidity greater than the rigidity of the material forming the body.</p> |
