ABSTRACT:
A reusable device for connecting hose or tubing to a hole in the panel of machines, vacuum motors, and the like, that can be installed and removed by hand. Installation requires no special skill, tools, or panel preparation, and does not alter the panel in any way. Once installed, hose or tubing can be clamped onto the device by a conventional way. The device consists of three interlocking parts assembled in the order in which they are presented in FIG. 1. Part A is a flexible tubular body with a flange (11) at one end and a slotted section (17) along its length. When the body is squeezed together the diameter of the flange (11) is reduced, allowing it to pass through the hole in the panel. Once inserted into the hole, and the pressure released, the diameter of the flange (11) expands. The flange, once again larger than the diameter of the hole, secures the tubular body in the panel. Part B is an insert that fits into the slotted section (17) of Part A and completes the tubular shape of Part A. The insert prevents the tubular body from being deformed by any pressure on its outer diameter and helps secure the tubular body in the panel. Part C is a tubular ring which snaps into the inner recessed area (14) of Parts A and B. The tubular ring prevents Part B from being pushed out of the slotted section (17) of Part A by any force on its outer diameter. The ring also adds structural support to the device enabling it to support the pressure applied when hose or tubing is clamped onto it by a conventional way.
