Abstract

The invention relates to a hydraulic quick connector comprising: a coupling sleeve (2) having a coupling end and an opposite connection end for connection with a fluid line; a nipple (1) having an insertion end and a connection end for connection with a fluid line, which nipple is insertable with the insertion end into the coupling sleeve at the coupling end; and a releasable lock for blocking the nipple in an inserted position, wherein the nipple is inserted into the coupling sleeve; and an electric contact ring (42) for ensuring electrical contact between the coupling sleeve and the nipple in the inserted position, which contact ring is mounted in a circumferential groove arranged in the coupling sleeve, wherein the contact ring is a coiled wire having at least one winding with a discontinuous curvature.
