A compact expanding barrier which provides great ﬂexibility in terms of length, which other barriers do not have. When closed, it is 55 cm wide and takes up minimal space in a storage, and it can be expanded to 310 cm. Weighing only 10,5 kg and being 1 m high, it is light, both in regard to transport and manipulation, and simultaneously strong enough to remain stable in case of wind and on uneven ground. Each barrier has a functional connector which keeps it securely closed during transport or in storage. The connector can also be used to connect several barriers into one whole.
