The clip is adapted to snap onto the pipe to be prepared so that the cutter assembly is pressed against the surface of the pipe. The assembly comprising a substantially cylindrical body which has a flat or concave face (34) through a slot (28) in which a cutter element (24) protrudes. The flat or concave face is adapted to bear against the surface of the pipe and to maintain the cutter element in contact with the pipe. The cutter element (24) has different edges at different angles to the axis of a shaft (20), on which it is mounted and which is rotatable in a housing (18) of the assembly, to cut a circular or helical groove in the surface of the pipe. |
