Can anybody recommend a supplier for plastic hose clips, not the jubilee clamp type but the ones that keep hoses apart in the engine bay. Often they consist of two hose clamps joined together and sometimes have a bracket attached for mounting on the car body.
The only thing I'm familiar with, that kind-of matches your description is what I've used on air-brake hose for semi-trailers that I work on. Examples of which can be seen here: http://www.ryderfleetproducts.com/ryder/af/ryder/core/nav/srm/oid/-9025/cn/Air-Fittings-and-Supports/erm/browse.do
