A first element is connected to a first end of the connecting piece and a second element is connected to a second end of the connecting piece. At least one end of the connecting piece is provided with a thread, whereby the connecting piece is connectable for instance to a pipe or fitting with threaded connection. The connecting piece may be made of plastic, for example, in such a way that a metal insert provided with a thread is arranged at at least one end of the plastic body of the connecting piece, or the connecting piece is made substantially completely of thermoplast in such a way that the thermoplastic body is provided with a thread. The outer surface of the connecting piece is provided with a gripping member. The gripping member is formed and dimensioned such that it gives way earlier than the connecting member thread and/or basic structure.
A connecting piece, intended for connecting at least two elements, whereby a first element is connected to a first end of the connecting piece and a second element is connected to a second end of the connecting piece, the connecting piece comprising a body mainly of plastic, at at least one end of the connecting piece a metal insert provided with a thread, whereby at least one element is connectable to the connecting piece with threaded connection and at least one gripping element on the outer surface of the connecting piece for rotating the connecting piece or keeping it still upon making the threaded connection, the gripping element comprises at least two straight portions such that two straight portions on opposite sides of the connecting piece are parallel, the straight portions forming gripping surfaces for a tool, and portion which is arranged smooth between adjacent straight portions, whereby the gripping element is formed such that the tool round the gripping element slips before the thread and/or the basic structure of the connecting piece gets damaged.
