Abstract
A hose coupling for connecting two hoses (3, 4) has two hose fittings (1, 2), which each have a coupling part (5, 6). One coupling part (5) has a radially encircling guide collar (7), which engages in a groove (9) made in a sleeve (8) of the other coupling part (6). The sleeve (8) is of elastic material in order to fit the coupling parts (5, 6) one inside the other in a simple manner.
Claims10
A hose coupling intended for connecting a hose to a second component and for hoses which are to be changed infrequently, in particular for a windshield washer unit of a motor vehicle, having a hose fitting designed so that a hose can be slipped onto it, wherein the hose fitting (1) and the second component (hose fitting 2) each have a coupling part (5, 6), and wherein one of the coupling parts (5) has a radially encircling guide collar (7) and the other coupling part (6) has an elastic sleeve (8) with a groove (9), the groove (9) corresponding in width and diameter to the guide collar (7) of the one coupling part (5) engagingly locking and sealing said part against leakage.
A hose coupling, in particular for a windshield washer unit of a motor vehicle, comprising
- two hose fittings which at one respective end are formed such that a hose can be slipped onto them, and each hose fitting has a coupling part at their respective other end, one said coupling part having an elastic sleeve with a groove and the other said coupling part having a radially encircling guide collar, there being only two of said coupling parts,
- the groove of said one coupling part corresponds in width and diameter to said guide collar of said other coupling part, said collar and said groove engagingly locking together and sealing the coupling parts against leakage, and
- said guide collar, toward a free end of said other coupling part, merges into a cone of decreasing diameter, a smallest diameter having a large clearance relative to an inside diameter of said elastic sleeve.
