A plug-type coupler consisting of male part (P) and female part (M), particularly for the connecting of conduits (2, 3) conducting fluids (4), which coupling has, within the region of the abutment place (1) between male part (P) and female part (M), a metallic ring packing (D) which is expandable in its cross section as a result of its arrangement and of a surface slot (18) by fluid (4) which is under pressure and, in this connection, rests in part on the male part (P) and in part on the female part (M), and, in order to obtain a solution which is simple in manufacture and reliable in use, the ring packing (D) which is arranged on the male part (P), with its slot (17) facing radially inward is gripped over, on the other side of the slot edge lying in the insertion direction (arrow x) by an annular shoulder (24) from which there extends a frustoconical surface (25) which tapers down towards the axis (y-y) of the plug-type coupler and opposite which there is a mating surface (27) of the female part (M) which extends into an abutment surface (14) which urges the ring packing (D) in insertion direction (x), the frustoconical surface (25) and the mating surface (27) permitting the passage of fluid up to the ring packing (D).
