International ClassB65D 063/02Foreign Application Priority Data1989-06-26 JPAbstractA hose clamp includes an annular clamp body having a pair of opposite end parts intersecting each other and bent in a radially outward direction so as to effect radial expansion of the clamp body by mutual approximation of the end parts. One of the end parts has a lock depression formed therein. The other end part has a lock claw part formed thereon at a position capable of engagement with the lock depression. The one end part has an unlocking wall formed thereon for disengaging the lock claw part from the lock depression. The clamp body is retained in a radially expanded state by the engagement between the lock claw part and the lock depression and is allowed to contract by the disengagement between the lock depression and the lock claw part. | |
