Patent ID: 8128126

Claim:
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 different from the first diameter; and a coupling device to couple the at least two corrugated conduits together, said coupling device comprising: a first side having a first snap fitting mechanism; a second side having a second snap fitting mechanism, said first snap fitting mechanism mating with the second snap fitting mechanism to releasably secure the first side to the second side and form the coupling device, said coupling device having a main body communicating with a first opening, a second opening and a third opening; wherein said first opening, second opening and third opening engage at end of each of the at least two corrugated conduits by fitting into a corrugation near the end of each of the at least two corrugated conduits when the first side is releasably secured to the second side, and wherein each of the first opening, the second opening and the third opening have a conical end with pre-scored cut lines aligned with opening ribs along each conical end to permit the conical end to be cut at one of the pre-scored cut lines corresponding to the first diameter or the second diameter, such that the opening ribs having the first diameter or the second diameter engage the corrugation of the at least two corrugated conduits having the first diameter or the second diameter.
