A clamping device (10) for clamping a hose, boot or the like (12) to a cylindrically-shaped structure (14) is disclosed. The clamping device (10) is a clamping band (20) having a body portion (28), an underlap end (34) having a pair of hooks (40) adjacent thereto, an overlap end (42) having a pair of shoulders (50) adjacent thereto for engaging the pair of hooks (40), and a clasp (52) for binding the overlapped portion of the clamping band (20) adjacent the overlap end (42). The overlap end (42) is elevated above the body portion (28) of the clamping band (20) so as to accommodate the underlap end (34) therebelow. As a result, no gap beneath the clamping band (20) is formed where the overlap end (42) extends radially outward to overlap the underlap end (34). Further, the profile of the clamping band (20) is limited to four thicknesses of the body portion (28) outside the perimeter of the hose or boot (12).
