The present connector for liquid-conducting, plug-type connections consists of a hose nipple (2) formed on the coupling (1) and pluggable into the connecting end of a flexible plastic hose (3). The nipple has at its free end a conically widening, beveled plug edge (4) and an adjoining cylindrical shaft portion (5) with several truncated expansions (6) and (7), as well as an annular contact flange (8) at the end of the plug-in area (E) portion. The back side of the first truncated expansion portion (6) has a conical taper portion (9). Between the expansion portion (6) and the taper portion (9) an encircling groove (10) is provided, in which is embedded a gasket ring (11) circular in cross section. In order that the end of the hose or tube can be easily slipped over the nipple and the gasket ring, the surface (M1) of the first truncated expansion portion (6) outwardly at an angle .alpha. of about 45.degree. in relation to the surface of the shaft (5) and is oriented so as to provide a slight clearance (a) past the outer surface (14) of the gasket ring (11). The surface (M2) of the succeeding taper portion (9) has a significantly flatter angle of inclination .beta. of about 20.degree.-30.degree. in relation to the surface area of the shaft (5) and its rearward projection is tangent to the outer surface (14) of the gasket ring.

[ We claim:] [1.] A connector adapted for insertion into a flexible plastic hose, said connector comprising a gasket ring having an outer surface, a nipple having a beveled free end, and a contact flange, said nipple further having a cylindrical shaft portion extending from said free end to a truncated expansion portion, said nipple further having a tapered portion and an annular groove positioned between said expansion portion and said tapered portion; said gasket ring positioned in said angular grove, said truncated expansion portion having a surface angling outwardly from said shaft at an angle in the range of between 40.degree.-46.degree., such that an outward projection of said surface freely clears said outer surface of said ring, said tapered portion having a surface angling inwardly from said annular groove at an angle generally in the range of 20.degree.-30.degree. such that a projection of the surface is tangent to said outer surface of said ring.
