1. Hose connector for connecting hoses to hose couplings, the hose connector comprising:
- a basic body having a circular socket extending along an axis, over which a hose end of a hose can be fitted, and a bush, the bush at least partially, radially surrounding the hose end and the socket;
gripping elements formed at a free end of the bush, the gripping elements being movable towards the socket for engaghement with a hose end;
an external thread proveded at an outer circumference of the basic body;
a two-part sleeve screwably connected to the thread, the two-part sleeve having a screw part, a sleeve part and connecting means between the sleeve part and the screw part, the connecting means allowing the sleeve part to remain rotationally stationary and to be driven along the axis by the screw part as the screw part is rotated and thereby screwably connected to the thread;
the sleeve part having a surrounded portion, the surrounded portion having an actuating surface urging the gripping elements towards the socket to press against a hose fitted on the socket;
the sleeve part further comprises an extension portion having a length projecting axially beyond a free end of the socket;
and wherein the length is at least equal to the outer diameter of the socket.

Abstract
A hose connector with gripping elements (18) pressing a hose (14) on a socket (15) uses a two-part sleeve (24). The two-part sleeve includes a screw piece (25) and an extension sleeve connected to the screw piece by a rotary connection and the two-part sleeve surrounds and supports the hose for a significant portion beyond the clamping area of the gripping elements (18). This inner sleeve (32) also has the funnel-shaped, conical actuating surface (33) for the pressing of the gripping elements.

12. Hose connector for connecting hoses to hose couplings, the ho se connector comprising:
-
a basic body having a circular socket extending along an axis, over which a hose end of a hose can be fitted, and a bush, the bush at least partially, radially surrounding the socket; gripping elements formed at a free end of the bush, the gripping elements being moveable towards the socket for engagement with a hose end; an external thread provided at an outer circumference of the basic body; a two-part sleeve screwably connected to the thread, the two-part sleeve having a screw part, a sleeve part and connecting means between the sleeve part and the screw part; the connecting means allowing rotation of the screw part around the axis relative to the sleeve part, and the connecting means preventing movement of the screw part relative to the sleeve part in a direction along the axis towards a closed end of the socket as the screw part is rotated and thereby screwably connected to the thread; said sleeve part having a surrounded portion and an extension portion, the surrounded portion being at least partly surrounded by the screw part, and an actuating surface of the surrounded portion urging the gripping elements towards the socket to press against a hose when fitted on the socket; and
, a length of the extension portion projecting axially beyond a free end of the socket. - View Dependent Claims (13)
