Multi-layer composites, particularly thermoplastic composites, in form of an extruded hollow section, e.g. tubes or hoses for liquid fuel lines, include a thermoplastic outer layer and at least one further layer, wherein the outer layer is formed by a mixture based on 

Multilayer composite in form of extruded hollow sections

The invention relates to a housing from a polyamide molding compound containing 70 to 99.5% by weight of at least one thermoplastic polyamide and 0.5 to 30% by weight of at least one polyamide oligomer with linear or branched chain structure with a number average molar mass of 800 to 5000 g/mol with basic end groups which are at least partially NHend groups, and carboxyl end groups, one of these end groups being present in excess and the concentration of the end group present in excess being at most 300 mmol/kg.
