Abstract
Connecting the two band ends 10, 18 of a hose clamp is done by means of a guide hook 16 disposed on an inner band portion and engaging a guide hook receiving means 12 on the outer band end 10, and a support hook 17 also formed on the inner band portion and engaging a support hook receiving means 13 on the outer band portion. The support hook receiving means 13 is an embossment formed from the band material by cold deformation and being continuous with the band material on all sides, the inner surface of the support hook receiving means 13 having a support portion 25 adjacent to the outer band end 10 and extending at right angles with respect to the band surface. The support hook 17 has a nose 26 which faces away from the inner band end 18 and has a cut edge which nicks into the support portion 25 of the support hook receiving means 13 when the hose clamp is tightened. Since the support hook receiving means 13 is entirely continuous with the band material, it has a much higher stability then conventional cut-outs or windows formed in the band.
