Abstract:
A hose clip comprising:a clamping ring comprising a leaf spring in the form of an annular band, said clamping ring having a first end and a second end, said first end including a circumferential opening having a predetermined length and being formed along a circumferential centerline of said clamping ring, said second end comprising a narrow portion extending along the circumferential centerline of said clamping ring;a first knob at said first end of said clamping ring and extending in a radial direction with respect to a center axis of said clamping ring, said first knob including an arch-shaped opening formed by said circumferential opening;a second knob formed at a distal end of said narrow portion and extending in the radial direction, said clamping ring being arranged such that said narrow portion at said second end is arranged within said circumferential opening at said first end and passes under said arch-shaped opening of said first knob such that said second knob confronts said first knob;an abutment face on a first surface of said first knob, said first surface facing away from said second knob;a single locking claw formed between a pair of slits in said narrow portion of said clamping ring, said slits extending from an edge of said narrow portion to substantially the circumferential centerline of said clamping ring, said locking claw extending in the radial direction such that said locking claw is operable to engage said abutment face so as to hold said clamping ring in a spread-diameter state, and is operable to disengage said abutment face so as to allow said clamping ring to contract into a reduced-diameter state; andan escape window in said first knob, said escape window being located adjacent to said abutment face with respect to an axial direction of said clamping ring so as to allow said locking claw to pass therethrough, wherein said locking claw is operable to be disengaged from said abutment face by inserting a jig between an edge of said arch-shaped opening and said locking claw so as to push said locking claw in the axial direction and into said escape window, whereby said clamping ring is released from the spread-diameter state.
