Abstract (en)
The plastic end part (2) has a tubular plug section (5) pushed into the core (1). The plug has several circumferential longitudinal ribs (7) with dovetail-shaped profile. The outer flanks of the ribs are approximately radial, and preferably merge with sharp edges into a V-shaped groove. The inner free ends of the ribs merge wedge-like into the outer surface of the plug section. The plug section has a slot and an expander element is inserted into its free end. Anchoring elements project from its outer circumference.

Ein rohrförmiger Ansatz (5) des Endteils (2) ist in den Kern (1) eingeschoben. Der Ansatz (5) hat benachbart dem freien Ende hakenartige Vorsprünge (11). Damit wird eine sichere Verankerung des Endteils (2) im Kern (1) auch bei wechselnden Klimabedingungen erreicht. <IMAGE>
