Abstract:
A pipe fitting (2) for a substantially cylindrical pipe (5), the pipe extending along and about a first axis (23) and having inner and outer cylindrical, substantially smooth, non-tapered, non-threaded surfaces with respective inner and outer, constant diameters, the pipe further having at least one open end (3'),said pipe fitting (2) having a main body (4) extending at least in part along a second axis (8) and a sleeve member (6) extending about said part of said main body and mounted for sliding movement relative to said main body between at least first and second positions spaced from each other along said second axis (8), said main body having means for preventing said sleeve member from being slid along said second axis beyond said first and second positions to thereby maintain said slidable sleeve member on said main body and wherein said part of said main body extends for a first distance along said second axis between two locations and said sleeve member extends between two ends (14, 38) along said second axis for a second distance less than said first distance, said sleeve member being positionable about said part with the ends (14, 38) of said sleeve member between said two locations,said main body (4) being positionable adjacent the open end (3') of said pipe (5) with said first (23) and second (8) axes substantially co-linear, said sleeve member (6) having two open ends (14, 38) spaced from each other along the second axis, said sleeve member further including a substantially smooth, non-threaded inner surface (34) tapering inwardly substantially from one (38) of the open ends of said sleeve member toward the other open end (14) thereof, said inner surface of said sleeve member having an inner diameter (42) adjacent the one open end (38) thereof greater than the outer diameter (13) of the outer cylindrical surface of said pipe, said inner surface (34) tapering down to a diameter (44) less than the outer diameter of the outer cylindrical surface of said pipe, said sleeve member in said second position having at least a section of said tapering inner surface (34) of said sleeve member extending about the open end (3') of said pipe and about at least a portion (21) of the outer surface of said pipe (5) adjacent the open end (3') thereof.
