Abstract: A one-piece hollow sleeve molded of an elastomeric vinyl has a cylindrical rear end portion for attachment to a flexible hose of central vacuum cleaning system and has a front end portion which is slidably frictionally engageable within the inlet opening of variety of inlet valves. The front end portion is formed with a series of specifically sized and located tapered zones of varying lengths and angles of taper which enable the sleeve to be used with a variety of inlet valves having various internal diameters and lengths. A metal band is seated in a recess formed in the front end portion between certain of the tapered zones and has a length and location enabling it to contact the various pairs of contact buttons of the various types and styles of inlet valves. This universal sleeve eliminates a different hose attachment sleeve being required for each of the most common inlet valves of the most popular central vacuum cleaning systems.

Abstract: An alignment device adapted to position an elongated member such as a cable or the like within the interior of an associated enclosure. The device includes a hollow collar adapted to be placed in a close surrounding relationship with an axial section of the elongated member. The collar includes a longitudinal split in the side wall thereof between opposed spaced apart collar peripheral ends. These ends may be moved apart from each other for installing the device on the elongated member and then moved back toward each other to place the device in a close surrounding operative position thereon. An adjustable locking means facilitates locking the collar at the peripheral ends in the operative position and simultaneously prevents axial displacement of the peripheral ends relative to each other. A plurality of supporting legs extend outwardly of the collar at spaced intervals therearound and include support feet.
