The hose clamp (1) fits round a hose end (2) in the form of a basically annular clamping body (3) with end zones (4,5) overlapping each other. In the clamped state, it is set to a certain dia. but a tool can be used to expand it against its inherent spring force to a second, greater, dia. ie. in its expanded state. In the first end zone, there is an engaging projection (6), set back from its outer front edge (7), which can be engaged with the second end zone (5) to achieve the expanded state. In the second end zone, there is an elongated recess to receive the correspondingly narrow first end zone. |
