Abstract
Abstract A dimensionally recoverable body, which is preferably heat-recoverable, has a body wall which is provided with a plurality of locking elements that are engageable with each other, or are engageable with corresponding elements located on a separate partition, to furcate the body into a plurality of channels. The body may be used for enclosing branch-offs in electrical cables in order to protect the enclosed branch-off from the environment.
