The rinsing device comprises a flexible connecting pipe which at one end is connected to a connecting element which may be attached to a fitting and at the other end bears a spray head with an actuating lever. The spray head is held on a holder, which protrudes outwardly from the connecting element. The connecting pipe comprises a flexible water feed pipe which is surrounded by a casing element, which is formed by a single spiral tension spring consisting of one piece. Said spiral tension spring consists of a first upright spring portion having a straight spring axis, a second curved spring portion attached thereto and a third, similarly upright spring portion having a straight spring axis, which is attached to the second spring portion. A tube-shaped protective casing extends around the casing element which protects the casing element from soiling.
