The nozzle spout is fixed to a joint that can be connected to a supply pipework. The spout (4) moulded body (6) is made from highly resistant to wear ceramic while its enveloping protection sheath (12) is elastic. The body has a collar (8) near the joint (1). The lip (13) of the sheath is applied to the collar edge (9) opposed to the joint, and the spout is fixed to the joint near the rebate by a cap screw nut (5). The body has a constant wall (10) thickness as far as its collar. The moulded body is tapered towards the mouth (11).
