ABSTRACT:
An interlocking split flange connector, with two or three bolt holes, for attaching two pipes or other conduit at attachable and mateable flanged conduit ends such as found in vehicle exhaust systems. Because of the interlocking and split characteristics of the connector it is not necessary to slip the connector over the conduit and can thus be used with the disassembly of parts which may be attached to the conduit ends. The connector is formed from the interlocking assembly of two substantially identical interlocking split members. Each of the assembled interlocking split members has a centrally located aperture and at least two bolt holes or fastening apertures, a first symmetry axis and a second symmetry axis perpendicular to the first symmetry axis. The central aperture is formed by a semicircular inner edge and two substantially straight interlocking edges. The central aperture is preferably symmetric about the first symmetry axis but alternatively may be symmetric about the second symmetry axis. Additionally, each of two substantially identical clamp members has an interlocking portion affixed to the first interlocking split member such that the interlocking portion of the first interlocking split member, when the two interlocking split members are assembled, interfits between the interlocking edges of the second interlocking split member. The interlocking portion may be preferably created from a removed portion of the material of the identical interlocking split member. The interlocking assembly of the two substantially identical interlocking split members creates the interlocking split flange connector having the central aperture and fastening apertures.
