A double-walled hose for a drip-watering installation which is intended to bring about an adequately metered watering of plants in market gardens and the like. The hose comprises a corrugated inner hose 12 and an outer jacket 20 on the outside of this inner hose. Special problems arise when using such watering hoses when they are to be adapted, and cut into suitable lengths, for being joined to the watering installation. These problems are solved by means of a ring-shaped intermediate section 33, 33', in which supply holes 58 and outlet apertures 60, respectively, are arranged and in which the outer jacket 20 has a distinct invagination, being formed between labyrinth sections 46 for the metered supply of water and adjoining barrier sections 50. <IMAGE> |
