Cheney Clips
Jaguar used Cheney clips on the coolant hoses, the steering rack bellows and the petrol filler hose.
C. W. Cheney & Son Ltd
Manufacturer of locks, latches, clips, buttons and hinges. Factory Road, Hockley, Birmingham
1920 Established by Charles William Cheney
1944 Patented the Cheney clip
1994 Company bought by Frantzen (Germany)
2000 Acquired by Cumberland Leasing Corporation
2001 Acquired by F.H.Tomkins Buckle Company Ltd. of Brockhurst Crescent, Walsall
They are distinguished from other clips (note not 'clamps') by having a round slotted screw head and screw perforations that do not go completely through the mild steel bands so as to protect the hose from damage. They were bright cadmium plated which mellows to grey with age. Markings should include the company name (one of two styles as below), the size, 'England', 'Double Grip' and AGS or BS number. The differences between AGS and BS are:
1. BS3628 "Specification for hose clips (worm drive type) for general purpose use" was issued on 31 March 1963. So Cheney clips marked BS3628 would be later than that date, how long after would depend on when Cheney signed up to the BSI spec (it was not compulsory), how long it took to re-tool and how long it took the BS marked clips to enter the supply line. The BS3628 specification has been withdrawn and no longer valid
2. AGS605 is an aeronautical standard for clips which was managed by Society of British Aircraft Constructors founded in 1916, known as SBAC, the UK's national trade association representing companies supplying civil air transport, aerospace defence, homeland security and space. It is now managed by ASD Standards Organisation. Specification AGS-605-012 "Clip, Hose (Type J) Assembly" is sill in valid, in its twelfth edition.
3. So BS3628 clips could only be on cars produced after March 1963 at the earliest, AGS.605 clips can be on any car as they were made and supplied to the aero industry (or car manufacturers depending on what Cheney had in stock) until production stopped in 1994. They could therefore appear on any age car.
Cadmium plated reproductions are available from XK's Unlmited (USA) and Bresco (UK) amongst others but they are not particularly strong, especially the smaller sizes:
Jubilee clips use the same size reference as Cheney:
For the 3.8 coolant hoses you require:
C2905/1 = Cheney 00 (4 off)
C2905/2 = Cheney 0 (4 off)
C2905/4 = Cheney 2A (6 off)
C2905/5 = Cheney 3A (2 off)
C2905/12 = Cheney 1X (2 off)
For the steering rack:
C2905/4 = Cheney 2A (1 off)
C2905/2 = Cheney 0 (2 off)
For the fuel tank:
C2905/1 = Cheney 00 (2 off)
C2905/7 = Cheney 5A (2 off)
For the oil filter return pipe:
C2905/2 = Cheney 0 (2 off)
Note 1: The vacuum hose clips C15886/5 (4 off) are not the Cheney screw type
Note 2: They are not a very good design as the mild steel stretches and the simple slotted screw makes tightening up difficult. Suggest you only put them were they can be seen or where you can easily get at them; for everywhere else use s/s Jubilee clips, especially the fuel tank unless you like the smell of petrol! If you are more interested in driving the car rather than showing it use s/s Jubilee clips everywhere for leak free motoring. Now you know why Jaguar added two bottles of Bar Leaks to every car's cooling system on the production line!
Note 3: Jaguar also used 'Regent' clips at various times but never 'Jubilee' clips as far as we know
Note 4: Cheney also made clips in metric sizes which were supplied to Ferrari and Maserati amongst others. These have different markings stamped on them.
