A self tightening hose clamp is disclosed, having a band for encircling at least a portion of circumference of a hose and a bolt which extends from a left end of the band through the right end of the band and about the remaining portion of the circumference of the hose. A spring circumscribes an outer end of the bolt and applies a biasing force on the bolt and the right end of the band to maintain a clamping force between the band and the hose during contraction of the hose. A sleeve is disposed between the bolt and spring to coaxially center the spring about the bolt during compression.
