Abstract
A hose clamp includes an annular clamp body having a first terminal portion and a second terminal portion. The first terminal portion has a guide opening, a lock wall defined between the guide opening and the leading end of the first terminal portion, and side walls disposed across the guide opening and folded back over themselves in a substantially U-shaped cross section having an upper side piece and a lower side piece. The second terminal portion has a radially outwardly bent wall serving as an engaging tongue piece. The clamp body is kept in a radially expanded state when the engaging tongue piece of the second terminal portion abuts against the lock wall of the first terminal portion and is radially contracted when the abutment between the engaging tongue piece and the lock wall is released to move the engaging tongue piece within the guide opening.
