    • A connection piece (111) for a plug-in connection of a fluid-carrying system of lines for distributing drinking water within stories is formed without a supporting nipple. The connection piece (111) has in the region of an inner lateral surface of the first tubular part a first peripheral guiding surface (122) and a second peripheral guiding surface (117), arranged behind the first guiding surface (122) with respect to an insertion opening of the connection piece (111), for the second tubular part (160). A first axial extent of the first guiding surface (122) and a second axial extent of the second guiding surface (117) respectively make up each at least one sixth of an inside diameter of the first tubular part (112, 120). The connection piece (111) may form part of a fitting or a faucet and is suitable in particular for use with solid plastic pipes, for example of crosslinked polyethylene.
    • 形成用于在故障中分配饮用水的流体输送系统的插入式连接件的连接件(111),而没有支撑接头。 连接件(111)在第一管状部件的内侧表面的区域中具有相对于第一引导表面(122)布置在第一引导表面(122)的后面的第一外围引导表面(122)和第二外围引导表面(117) 用于第二管状部分(160)的连接件(111)的插入开口。 第一引导表面(122)的第一轴向范围和第二引导表面(117)的第二轴向范围分别构成第一管状部分(112,120)的内径的至少六分之一。 连接件(111)可以形成配件或水龙头的一部分,并且特别适用于固体塑料管,例如交联聚乙烯。
