Abstract
The pipe coupling for connection to a pipe end of a pipe made of polymer material comprises an inner sleeve (1) which is intended for insertion into the pipe end and for abutment with the inner surface of said pipe end, an outer sleeve which is intended for abutment with the outer surface of said pipe end and which includes a slot-like opening (14), and means for adjusting said opening (14). The coupling further comprises a pre-widening means positioned between the edges (21) of the slot-like opening (14). The pre-widening means makes the slot-like opening (14) larger such that the inner diameter of the outer sleeve (2) is larger than the outer diameter of the pipe.
