An improved band clamp for securely clamping the end of a flexible hose to one of at least a rigid pipe, a cast outlet of a radiator, a charge air cooler and a turbocharger in order to prevent fluid communication between the two. The improved band clamp includes a clamp band which is configured to circumvent a substantial portion of the hose. The clamp band defines first and second ends, each of which is defined by a terminal portion of the clamp band folded over on itself to define a double thickness, and then formed in an arcuate configuration away from the center of the clamp band. A spline is provided for being received between each of the first and second ends of the clamp band. First and second spacers are provided on the outer sides of the clamp band first and second ends. The first spacer, each of the first and second clamp band ends, and the spline each define an opening to cooperatively receive a bolt. The second spacer defines a threaded opening to receive the bolt in threaded engagement. The band defines a circumferential bead extending inwardly from the center of the band. An extender is carried within the band to extend between the terminal portions of the bead and to cover the gap between the first and second ends of the band. The extender is secured at one end to the inside of the band, with the other end remaining free to slide along the length of the band as the band clamp is tightened or loosened. The extender defines a bead along the entirety of its length to cooperate with the bead defined by the band.

1. A band clamp for securely clamping one end of a flexible hose to one of at least a rigid pipe, a cast outlet of a radiator, a charge air cooler and a turbocharger, said improved band clamp comprising:a band adapted to circumvent a substantial portion of the flexible hose, said band defining first and second ends, each of said first and second ends being formed to define an arcuate configuration having a convex side and a concave side, said convex side of said first end facing said convex side of said second end, said band defining a circumferential bead extending inwardly from a center of said band, said bead defining a first end terminating prior to said band first end and a second end terminating prior to said band second end, a gap being defined between said bead first end and said bead second end; a fastening device including a spline configured to be closely received between said band first and second ends, a first spacer disposed on said concave side of said band first end, a second spacer disposed on said concave side of said band second end, and a bolt, each of said first spacer, said band first and second ends and said spline defining a through opening for receiving said bolt, said second spacer defining a threaded opening configured to threadably engage said bolt; and an extender carried within said band to extend between said bead first and second ends to cover said gap, said extender defining a first end secured to an interior surface of said band proximate to and overlapping one of said bead first end and said bead second end, said extender defining a second end unsecured to said band in order slide along said interior surface of said band, said extender defining a bead extending inwardly entirely between said extender first end and said extender second end to cooperate with said band bead. 2. The band clamp of claim 1 wherein each of said band first end and said band second end is formed by folding over a terminal portion of said band to define a double thickness.3. The band clamp of claim 1 wherein each of said first spacer and said second spacer defines a convex interior surface and a flat exterior surface, said convex interior surface configured to closely engage said concave side of one of said band first end and said band second end.4. The band clamp of claim 1 wherein said spline defines first and second opposing concave surfaces configured to closely receive said convex side of said band first end and said band second end.5. In a band clamp for securely clamping one end of a flexible hose to one of at least a rigid pipe, a cast outlet of a radiator, a charge air cooler and a turbocharger, the band clamp having a band adapted to circumvent a substantial portion of the flexible hose, the band defining first and second ends, each being formed to define an arcuate configuration having a convex side and a concave side, said convex side of the first end facing said convex side of the second end, and a fastening device including a spline configured to be closely received between the band first and second ends, a first spacer disposed on the concave side of the band first end, a second spacer disposed on the concave side of the band second end, and a bolt, each of the first spacer, the band first and second ends and the spline defining a through opening for receiving the bolt, and the second spacer defining a threaded opening configured to threadably engage the bolt, an improvement comprising:a circumferential bead extending inwardly from a center of the band, said bead defining a first end terminating prior to said band first end and a second end terminating prior to said band second end, a gap being defined between said bead first end and said bead second end; and an extender carried within the band to extend between said bead first and second ends to cover said gap, said extender defining a first end secured to an interior surface of the band proximate to and overlapping one of said bead first end and said bead second end, said extender defining a second end unsecured to the band in order slide along the interior surface of the band, said extender defining a bead extending inwardly entirely between said extender first end and said extender second end to cooperate with said band bead.
