Abstract
The compression fitting (10) for a heating and/or sanitary pipe comprises a fitting body (12) including a supporting sleeve (16) adapted to have a pipe end (66) slid thereonto, and a conical abutment face (20). The compression fitting (10) further comprises a complementary part (24) for the fitting body (12), which is provided with a conical receiving face (22) for abutment by the abutment face (20) of the fitting body (12). The compression fitting (10) is provided with a clamping ring (40) encompassing the pipe end (66) which can be slid on the supporting sleeve (16), and with a lock nut (42) having an inner thread (44) and being adapted to be screwed to the complementary part (24), for pressing the clamping ring (40) against the fitting body (12) and for clamping abutment on the pipe end (66) in the condition when the pipe end has been slid onto the supporting sleeve (16). The fitting body (12) comprises radially protruding fixing projections (46) for axially fixing the fitting body (12) inside the lock nut (42) to the inner thread (44) or to other internal face structures thereof, to prevent the lock nut (42) from being inadvertently detached before it is screwed to the compleme…
