FIELD: machine building.
SUBSTANCE: invention relates to press-fitting comprising sleeve with insertion hole of pipe end (4). Annular groove-shaped space (11), which is available in squeezing wall part (10) of crimping area, is limited by limiting edge (12). Clamping ring (17) is located in annular chute-like space. Crimping area is deformed from uncompressed state into compressed state due to radially inward pressing action, leading to that squeezing wall part radially compresses, and clamping ring clamps pipe end. Control ring (19) comprises one or more fragile segments (32) and connecting part (26, 28).
EFFECT: fragile segments can be broken off as a result of crimping, at that, the connecting part becomes visible at least partially between the limiting edge and the pipe end.
