ABSTRACT:
A measuring device is provided, having a cylindrical connection piece (1), having a collar (2) which engages around at least one section of the connection piece (1) and is to be fastened at a measuring location, having a restraining means, by which the connection piece (1) is fastened in the collar (2), having an annular seal (3), which is arranged in the collar (2) and bears in a sealing manner against the connection piece (1), and having a thrust ring (4) which is releasably fastened in the collar (2), and, in an end position, puts the seal (3) under pressure in the axial direction, with which device mounting and demounting at the measuring location take place in one operation and with which device, during mounting, the fastening of the connection piece (1) takes place before or at the same time as the restraining of the seal (3), and with which device, during demounting, first of all the seal (3) is released and then the fastening. This is achieved by the restraining means being designed as a clamping means which can be released from a clamped state just by the action of an external force, and by the clamped state being effected by the end position of the thrust ring (4).
