<p>The invention relates to a line heating element for beverage-preparing devices, consisting of a water-conducting tube (1) and electric heating elements (3) directly or indirectly fixed thereto. The water-conducting tube (1) is tapered at the end, and the tapered zone (4) forms an insertion area for a water-conducting hose. The aim of the invention is to provide such a line heating element which is very inexpensive to produce and in which production-related losses of sealing tightness between the water-conducting tube and the tapered zone are prevented. This is achieved in that the tapered zone (4) is integrally molded on the water-conducting hose (1).</p> |
