This splice is normally used to connect two hose sections. But I used it to connect to a dust filter. I cut it in half, glued the two pieces in place, connected up a hose to each place and clamped them.. The dust filter connections are are set up to have the hose pushed in and are held in place by the ribs in the host. This works fine for normal hose, but not for extra-flexible hose. So this was how I fixed it when I changed hose types.
