the arc 14 is interfaced with a groove 2 while in other embodiments there is no groove 2 e g groove bead 27 is absent and the arc 14 is interfaced with a head bead 29 there are several beads 9 29 27 on the hollow rigid shaft 5 7 the bead 9 29 27 that aligns with the arc 17 is the head bead 29 the groove bead 27 is present in some embodiments to form the groove 2 between the groove bead 27 and the head bead 29 the clamp guide arms 16 have bumps 11 that align with the beads 9 see fig4 and registration areas 15 that are aligned between the beads 9 the hose clamps 30 see fig5 7 are placed over the clamp guide arms 16 such that the hose clamps 30 seat into the registration areas 15 in this way as the hose clamps 30 are tightened the flexible hose 20 is compressed in between the beads 9 providing a stronger connection between the flexible hose 20 and the rigid hollow shaft 5 7 thereby resisting separation under high pressure although two registration areas 15 are shown the present invention is not limited to any particular number of registration areas 15 and any number of registration areas 15 is anticipated including one registration area 15 it is.
