Thanks. Will check the clips later.
Zip tied the sleeve to the rear brake line and problem solved.
Am I right thinking the wires inside the sleeves are cabled/hosed too, correct? As in, the wires inside the sleeve aren't exposed? The dent isn't big enough to expose the cables inside, so can't check what the wires are like inside. Common sense would dictate the wires are cabled/hosed indeed, but might as well go ahead and ask this question.
I'll probably be adding some heatproof silicone to fill up the dent.
