<p>The invention concerns a connecting and branching piece (1) in the form of a base sleeve tube (2) intersected on one side by one or several secondary branching tubes (4). This piece opens up into two shells (13, 14) along a plane containing the sleeve tube and the secondary tubes, and linked by a hinge (5) along a rectilinear part on the other opposite rectilinear side of the sleeve tube. At least one of the secondary tubes has one or several grooves (20) at its intersection with the base sleeve tube, and/or the sleeve tube has one or several grooves between one of its ends and the intersection with the adjacent secondary tube. These grooves enable an easier orientation, closer to the sleeve tube, of a secondary tube in any direction.</p> |
