Image Number 4 for United States Patent #8128126.
A coupling device formed of two identical sides is disclosed. Each of the two sides have a snap fitting mechanism which engage each other to releasably secure the sides together thereby forming the coupling device. The coupling device as formed has a main body communicating with at least two openings. Each opening is sized to engage an end of a corresponding conduit. Generally, the conduits are corrugated such that the openings engage one corrugation to form the friction fit. The openings may be conically shaped with pre-scored cut lines that can be cut at different diameters to engage conduits of different diameters. The openings of the coupling device have pre-score cut lines that may be cut in order to create the friction fit with corrugated conduits having different diameters.
