Snap connection for connecting two tube ends

Abstract

The snap connection for sealed and releasable connection of a first tube end (10) with a second tube end (20), with spring arms (33), with a first outer stop projection (14) on the first tube end (10), with a first elastically deformable ring (31) connected with the spring arms (33), and with two first inner stop cams (34) on the first ring (31) cooperating with the first outer stop projection (14), is characterized according to the present invention by a second outer stop projection (23) on the second tube end (20), a second elastically deformable ring (32) connected with the spring arms (33) with distance from the first ring (31), and by two, second inner stop cams (35) on the second ring (32) cooperating with the second outer stop projection (23). Both rings with their stop cams, connected to one another via the spring arms, form a double-connection element (30) separable by and on both tube ends (10, 20), which can be made from a plastic injection molding part. The first tube end (10), for example, can be made by extrusion blow-molding and directly assembled with the second tube end (20), which can be a metal or plastic connecting piece, whereby the connection is fixed in a sealed position after the snapping of the double-connection element (30).
