PIPE COUPLING

摘要

The present invention relates to a pipe coupling for connection to a pipe end of a pipe made of polymer material and intended preferably for tap water or heating installations. The pipe coupling includes an inner sleeve intended for insertion into the pipe end and for abutment with the inner surface of said pipe end. The coupling further includes an outer sleeve intended for abutment with the outer surface of said pipe end. The outer sleeve is provided with a slot-like opening and means for adjusting the width of said opening. When the outer sleeve is in a tightened, adjusted state, the sleeve (2) will be internally and externally cylindrical. A centre axis (X) through the outer cylindrical surface (44) of the outer sleeve (2) is spaced at a distance (D) from a centre axis (Y) through the inner cylindrical surface (46) of the outer sleeve (2). In the tightened, adjusted state of the outer sleeve (2), the internal radius (B) of said sleeve is smaller than the external radius (C) of said pipe end (20).
