Abstract: A tether-harness combination is intended to restrain a group of children to provide security for the group during excursions, sightseeing trips, or when walking. The tether-harness is modular, and may accommodate an indefinite number of children by adding or removing modules. The master module includes a cruciate junction connector which mates, by quick-release connectors, with a master restraint strap held by a teacher, counselor, or other monitor controlling the children. The junction connector is also attached to one or more harnesses by similar quick-release connectors, and each harness used to harness a child to the device. In addition to the master module, the device includes an indefinite number of slave modules. Each slave module is attached to an adjacent module, using quick-release connectors, and a longitudinal connecting strap. Each slave module is also attached to one or more harnesses, these attachments also being made by quick-release connectors.
