Claim:
A system for detecting vehicles on a vehicle travel surface, comprising: a plurality of support carrier sections adapted for insertion followed by aligned attachment and sliding within a conduit extending under the vehicle travel surface, each support carrier section comprising: a body which is substantially rigid running longitudinally from a first end to an opposing second end, the body having: a left clip abutment wall extending vertically, a right clip abutment wall extending vertically and a horizontal clip abutment wall extending horizontally and integrally between the left and right clip abutment walls; and a retention groove extending horizontally in the left and right clip abutment walls; a clip recess defined in the body adjacent the first end of the body; a clip adjacent the second end of the body, the clip having a prong which deflects against a spring force to be tactilely receivable in the clip recess of a next aligned support carrier section; and a release lever for the clip, the release lever extending upwardly and exposed for manual depression to overcome the spring force and move the prong to a release position relative to the clip recess; and tabs on the clip, the tabs engaged with the retention grooves on the left and right clip abutment walls.
