Clamps

There are three types of clamps originally used on the 330 GT.  These are Cheney, copiglia and Corbin clamps.

COPIGLIA CLAMPS

The copiglia clamps are used on the heater hoses, radiator overflow, cowl drain hoses, heater and defrost hoses, etc.  They come in 2 widths, 5mm and 9mm.

Manual heater valves†Cowl drain, by fuse box
Radiator overflow hose†Radiator overflow hose at overflow tank†
Defroster hose under dash

CORBIN CLAMPS

Corbin (spring wire) clamps are used for small hoses where there is no pressure.  Their main purpose is to prevent the hose from slipping off rather than a tight seal.

CHENEY CLAMPS

Cheney clamps are similar to the normal hose clamps you would buy at any auto supply store.  The main difference is that the band is not slotted for the screw threads.  Instead, the band has indentations for the threads.  These are common on English cars of the same era, so a source might be a Jaguar garage's old parts box.

Here are the locations and types of the various clamps, as derived from the Ferrari and Pininfarina parts books.
