An element (10) for transmitting pushing and pulling forces as well as torque with a straight configuration and a bent configuration comprises a base plate (12), an end plate (14) and bellows (16) arranged between the base plate (12) and the end plate (14). The base plate (12) and the end plate (14) are connected with a connecting element. A plurality of washers (18) is arranged within the bellows (16), the washers (18) having a tronconical shape at at least one of their major surfaces. The washers (18) are in mutual contact with each other or with the base plate (12) or the end plate (14) respectively, both in the straight configuration and the bent configuration, such that element can transmit pushing and pulling forces both in the straight configuration and the bent configuration without substantially changing the length of the element (10) ( Fig. 1 ).
