Device and method for coupling a conduit

A coupling system comprising:

• at least two corresponding corrugated conduits, wherein at least one corresponding corrugated conduit has a first diameter and at least one corrugated conduit has a second diameter larger than the first diameter;
• and
• a coupling device to couple the at least two corresponding conduits together, said coupling device comprising:
• a first side having a first perimeter;
• a second side, separate from the first side, having a second perimeter;
• a first snap fitting mechanism extending along at least a first portion of the first perimeter;
• a second snap fitting mechanism extending along at least a second portion of the second perimeter, said first snap fitting mechanism mating with the second snap fitting mechanism to releasably secure the first side to the second side to form the coupling device, said coupling device having a main body communicating with at least two openings;
• wherein said at least two openings are each sized to create an interference fit with an end of the at least two corresponding conduits when the first side is releasably secured to the second side;
• wherein said at least two openings each form an interference fit with the end of the at least two corresponding corrugated conduits by being sized to have an opening rib fit into a corrugation of the at least two corresponding corrugated conduits;
• and
• wherein the at least two openings each have a conical end with pre-scored cut lines aligned with corresponding opening ribs along the at least two openings to permit the conical ends to be cut at the first diameter or the second diameter, such that, after the conical ends are cut at one of the pre-scored cut lines aligned with the corresponding opening ribs, the conical ends have opening ribs which engage the corrugation of each of the at least two corresponding corrugated conduits having the first diameter and the second diameter.

A method of coupling conduits, said method comprising:

• providing a first side of a coupling device, said first side having a first snap fitting mechanism and at least two U-shaped channels;
• providing a second side of the coupling device, separate from the first side, said second side having a second snap fitting mechanism which mates with the first snap fitting mechanism;
• providing at least two corresponding corrugated conduits, wherein at least one corresponding corrugated conduit has a first conduit diameter and at least one corrugated conduit has a second conduit diameter different from the first conduit diameter, and wherein the at least two U-shaped channels of the first side and the second side are tapered and have pre-scored cut lines corresponding to the first conduit diameter and the second conduit diameter with opening ribs to engage corrugations of the first conduit diameter or the second conduit diameter such that the at least two U-shaped channels form openings sized to create an interference fit with the ends of the at least two corresponding corrugated conduits;
• severing a section of the at least two U-shaped channels of the first side and the second side at the pre-scored cut lines to match one of the first conduit diameter or the second conduit diameter corresponding to each of the at least two corresponding corrugated conduits;
• placing in each U-shaped channel an end of one of the at least two corresponding corrugated conduits;
• and
• releasably securing the first side to the second side by mating the first snap fit mechanism to the second snap fit mechanism to form the coupling device such that at least the two U-shaped channels of the first side mate with at least two channels of the second side to form at least two openings sized to engage the ends of the at least two corresponding corrugated conduits with the opening ribs of the at least two openings forming the interference fit with the at least two corresponding conduits by having the opening ribs associated with one of the pre-scored lines sized to fit into a corrugation near an end of the at least two corresponding corrugated conduits when the U-shaped channels of the first side and the second side are severed at the pre-cut score line.
