1. A dual cam lever hose clamp, comprising:
first and second cam lever clamps, each configured to move between a retaining position and a release position; and
upper and lower clamp halves adapted to form a collar when first ends of said upper and lower clamp halves fasten each other via said first cam lever clamp and when second ends of said upper and lower clamp halves fasten each other via said second cam lever clamp;
wherein said first cam lever clamp comprises:
a first linkage pivotally coupled to said first end of said lower clamp half and adapted to traverse through first grooves vertically and serially disposed on said first ends of said upper and lower clamp halves when said first cam lever clamp is in said retaining position, such that said first linkage is received within said first grooves of said upper and lower clamp halves; and
a first cam lever pivotally coupled to said first linkage and adapted to fasten said first ends of said upper and lower clamp halves when a first cam follower cammingly engages a first cam surface of said upper clamp half, said first cam lever having an elongate and substantially curved shape and extending beyond a center of said upper clamp half; and
wherein said second cam lever clamp comprises:
a second linkage pivotally coupled to said second end of said lower clamp half and adapted to traverse through second grooves vertically and serially disposed on said second ends of said upper and lower clamp halves when said second cam lever clamp is in said retaining position, such that said second linkage is received within said second grooves of said upper and lower clamp halves; and
a second cam lever pivotally coupled to said second linkage and adapted to fasten said second ends of said upper and lower clamp halves when a second cam follower cammingly engages a second cam surface of said upper clamp half, said second cam lever having an elongate and substantially curved shape and extending beyond said center of said upper clamp half, such that said second cam lever is configured to overlap and obstruct said first cam lever when said first and second cam lever clamps are in said retaining position;
wherein said second ends of said upper and lower clamp halves each comprise a through-hole configured to secure together said second ends of said upper and lower clamp halves via a fastening device.
