Abstract

The invention relates to a connecting device, preferably a pipe coupling, whose housing (13) is equipped with a deformable indicating element that is provided in the form of a, for example, springy finger (18, 19). When tightening the pipe coupling, the finger (18, 19) is subjected to the action of the sealing collar (14) from the inside and is thus outwardly deformed in a manner that is proportional to the pressure. This enables the tightened state of the pipe coupling to be identified from the outside without the use of auxiliary means.
