The press fitting for a pipe, is provided with a fitting body which has a supporting sleeve with a free end and a pressing sleeve. The pressing sleeve is held substantially concentrically with respect to the supporting sleeve by means of at least one spacer element arranged at the holding end of the pressing sleeve. I the region of the holding end of the pressing sleeve, the fitting body has a locking depression or a locking projection. At the holding end, the cylindrical wall of the pressing sleeve has at least one opening through which a locking element extends to the axial fitting of the pressing sleeve to the fitting body, wherein the locking element projects into the locking depression of the fitting body and ends in the depression, or the locking element engages around or behind the locking projection of the fitting body.

Press fitting for a pipe, in particular plastic pipe or plastic and metal composite pipe

A fitting for a pipe, has a base body and a connecting body, each having a passage for a fluid. Both bodies include contact surfaces that can be slid into each other, including at least one pair of opposing recesses forming a receiving chamber. The fitting has a flexible, substantially incompressible locking element that can be inserted into the receiving chamber for fixing the two bodies together. At least one of the two bodies includes an access chamber extending between an outer surface of the associated body and the receiving chamber. The access chamber connects to and is an extension of the receiving chamber. The locking element includes a stop protrusion at one of its opposite ends for stopping the locking element externally at least one of the two bodies in order to prevent the locking element from unintentionally slipping out of the receiving chamber.
