hose clip driver is a specially designed screwdriver-like tool which
is used to easily loosen or tighten the fasteners on hose clips.
A hose clip driver consists of a handle, flexible shaft which can
access areas a rigid shaft cannot, and a hexagonal drive head which
fits over the hose clip fastener.
If a hose clip driver is not available a regular flat head screw
driver or correctly sized hexagonal socket can be used to release
or tighten hose clips.
