If there aren’t any super narrow things they’ll need to pass through, tape works well. Specifically one that won’t leave residue and won’t add extra friction would be best. I’ve used electrical tape before.
Put the head of the cable you’re pulling parallel to the existing cable and tape down from the single cable to also cover the head and a 6" to a foot or so of the pulled cable. That way he head won’t catch, and the tape won’t unravel.
