Fitting and joining arrangmenent having a fitting

A joining arrangement comprising:

• a fitting including a connecting section having a circumferentially-extending groove, a sealing element arranged in the groove, and a protection sleeve configured to be arranged in the groove and displaceable between a first position wherein the protection sleeve covers the groove and a second position wherein the protection sleeve exposes the groove at least partially, and an amount of exposure of the groove is greater in the second position than an amount of exposure of the groove in the first position;
• a pipe configured to allow a medium to flow therethrough, the pipe having an end connected to the fitting,
• wherein the protection sleeve includes a stop, which stop is configured to interact with the pipe end to move the protection sleeve relative to the connecting section;
• and
• wherein the protection sleeve includes one of a radial expansion and a radial contraction formed thereon engaging the pipe end.

A method for producing a joining arrangement, the joining arrangement including a fitting having a connecting section with a circumferentially-extending groove and a sealing element arranged in the groove, the method steps comprising:

• providing a protection sleeve arranged in a first position on the connecting section covering the groove;
• pushing a pipe end one of onto and into the connecting section;
• displacing the protection sleeve in an axial direction to a second position in which the groove is at least partially exposed;
• and
• wherein in the first position the protection sleeve covers the groove at least partially and in the second position the protection sleeve exposes the groove at least partially, and an amount of exposure of the groove is greater in the second position than an amount of exposure of the groove in the first position;
• and
• wherein the pipe end interacts with a stop of the protection sleeve, which stop has a conical shape at least in sections, and interaction of the stop with the pipe end and a cutting element interacting with the pipe end cause a clamping of the pipe in the fitting and produces the joining arrangement.

A fitting for connection with a pipe end configured to have a medium flow therethrough, the fitting comprising:

• a connecting section having a circumferentially-extending groove;
• a sealing element arranged in the groove;
• a protection sleeve configured to be arranged over the groove and displaceable between a first position and a second position;
• wherein in the first position the protection sleeve covers the groove and in the second position the protection sleeve exposes the groove at least partially, and an amount of exposure of the groove is greater in the second position than an amount of exposure of the groove in the first position;
• wherein the protection sleeve includes a stop, which stop is configured to interact with the pipe end to move the protection sleeve relative to the connecting section;
• and
• wherein the stop has a cross-sectionally curved shape at the side of the stop facing the pipe end when pipe end is inserted.
