FIELD: machine building.
SUBSTANCE: invention relates to a pipe coupling comprising an annular clamp housing that has ends which are provided with two opposing clamp members. One or more tightening elements are provided for tightening the clamp members towards each other in a direction transverse to an axial length of the annular clamp housing so as to apply a radially-inward clamping force on a pipe being clamped in the annular clamp housing. Annular seal is mounted in the annular clamp housing. Annular clamp housing includes one or more enhanced circumferential stiffening elements.
EFFECT: invention provides uniform circumferential tightening of the coupling.
