Abstract
A video pipe inspection system may include a push-cable, camera head, and pipe guide having a pair of cylindrical shells, with each shell having a plurality of radially extending circumferentially spaced vanes and structure for holding the shells together when the shells are axially mated end-to-end. A pair of curved tab arms may extend circumferentially about corresponding ones of the cylindrical shells. A pair of slide-locks may be configured to slide over corresponding ones of the tab arms to move them into a locking position in which keys on the tab arms extend between adjacent coils of a coil spring surrounded by the shells.
