Abstract:
1. A connection system, comprising: a fitting comprising a hollow cylinder that tapers outward near one end to define a connecting socket at the end of the fitting, wherein the connector socket has a central axis and at least one radially outward directed ridge, in which a sealing element is provided; a pipe having an end with circular cross-section, wherein the end of the pipe is disposed inside the connecting socket of the fitting; wherein the connecting socket defines an internal surface that has a symmetrically non-round shape over the entire axial length of the connecting socket, with a smallest internal dimension and a greater internal dimension, wherein the external diameter of the end of pipe is smaller than the smallest internal dimension of said connecting socket to provide guidance for the end of the pipe for fitting by the smallest internal dimension and to form at least one axial gap that is axially aligned with the central axis; and said at least one axial gap extends over the entire connecting socket along its axial length between the internal contour of said connecting socket with a greater internal dimension and the end of pipe, and wherein the axial gap produces a deliberate leak point.
