The present invention concerns a small and neat harness (1) of light weight, which may be carried by the child as a garment, and which gives the child ample freedom of movement when it walks on its own, yet support while being carried. The harness may swiftly be coupled to and from a carrying strap (14) in order to carry the child, or for example to a pram or chair as a safety harness. The harness (1) may in addition be used as a walking or safety harness when the child wants to walk by itself.
