Abstract:
A two-part preassembly of a hose-like member and of a partially tightened clamp structure on said hose-like member, said partially tightened clamp structure including a clamping band means and a tightening means consisting of a plastically deformable ear means with two outwardly extending leg portions interconnected by a bridging portion, said ear means being already partially plastically deformed and being operable to be fully tightened, the preassembly of the hose-like member and of the partially tightened clamp structure, in which the clamp structure is already sufficiently secured on the hose-like member to maintain its predetermined final position to prevent relative movement therebetween at least in the circumferential direction, being supplied as preassembled parts to reduce the work required to complete the installation of said subassembly on a relatively fixed part to which the hose-like member is to be fastened by subsequent complete tightening of the clamp structure, and complementary engageable means in said clamping band means and in said hose-like member at predetermined locations relative to said ear means for positionally securing said clamp structure in its partially tightened preassembled condition corresponding to its final position on said hose-like member against relative movement between said clamp structure and said hose-like member in the circumferential direction and in at least one axial direction, and said complementary engageable means being located at least along one side of the clamping band means.
