Abstract: A hose connection piece (2), on which a sleeve-shaped insertion part (15) is arranged in the region of the outlet (14) of the passage channel (13) formed by a hose nipple (5) of the hose connection piece (2) and which is to be fastened on the nipple base body (12) of the hose nipple (5) by a snap-action or latching connection (16). The insertion part (15) can carry a sealing ring (7) for the contact flange (6) of the hose nipple (5) and/or axially secure a backflow preventer cartridge (26) which is introduced into the receiving space (25) of the hose nipple (5).

Abstract: In a hose arrangement (1) for a water-conveying system, which arrangement includes a flexible pressure hose (2) and a connection piece (4) with a hose nipple (5) and a ferrule (6) which receive the pressure hose (2) therebetween, it is provided that the ferrule (6) has an inwardly protruding projection (12) in a ferrule section (11) projecting axially beyond the hose nipple (5), by which projection the pressure hose (2) is displaced radially inwardly behind the hose nipple (5) to form a constriction (19) of the inside diameter such that a transition of the inside diameter between the hose nipple (5) and the pressure hose (2) is smoothed.

Abstract: A hose nipple (4) for a hose arrangement (1) is provided, having retaining ribs (6) on the outer side. According to the invention, the retaining ribs (6) vary in their form, size and arrangement on the nipple base body (5) between the hose side (12) and the outlet side (11) of the hose nipple (4) such that a uniform and parallel input of force into the pressure hose (2) is achieved by the retaining ribs (6), which causes the force- and/or form-fitting connection between the hose nipple (4) and the pressure hose (2) fitted thereon.

Abstract: A hose coupling is sleeve-shaped form and which, at at least one coupling end, has a connector with a retention profiling provided on the outer circumference at least in one connector subregion, onto which at least one profiled coupling end a hose end of a flexible hose can be pushed. The hose coupling according to the invention is characterized in that the retention profiling is formed by at least one retention groove which is provided on the outer circumference of the connector and which has groove long sides oriented in the connector circumferential direction and groove narrow sides oriented in the connector longitudinal direction.

Abstract: A hose coupling is provided, which is of sleeve-shaped form and which, at at least one coupling end, has a connector with a retention profiling provided on the outer circumference at least in one connector subregion, onto which coupling end a hose end of a flexible hose can be pushed. The retention profiling is formed by at least one retention groove, which is provided on the outer circumference of the connector and which has groove long sides oriented in the connector circumferential direction and groove narrow sides oriented in the connector longitudinal direction. The at least one retention groove has a groove base which is of flat form.

Abstract: A hose coupling (1) is provided, having a sleeve-like configuration and at least one coupling end with a connector (3), at the at least one coupling end, with a retaining profile provided on the outer circumference of at least one connector sub-region, it being possible for a hose end (4) of a flexible hose (2) to be pushed onto said at least one profiled coupling end. The retaining profile is formed by at least one retaining groove (5) which is provided on the outer circumference of the connector (3) and has longitudinal groove sides (8, 9) oriented in the circumferential direction of the connector and narrow groove sides (6, 7) oriented in the longitudinal direction of the connector.

Abstract: The invention relates to a method for cutting a tube segment (1) from a tube, said tube being provided with an inner tube (2) and an outer tube casing (3) surrounding the inner tube (2). Said the tube segment (1) is separated from the tube, by means of a cutting tool, at a cutting point in a cutting plane oriented transversely to the longitudinal extension of the tube. The tube casing (3) of the tube is surrounded by a separable tube retainer (4), which covers the provided cutting point before the tube segment (1) is separated from the tube, by means of the cutting tool, at the cutting point, wherein the tube retainer (4) completely surrounds the outer tube casing (3) in a peripheral direction.

Abstract: A detachable plug connection including a tubular insert part having a retaining projection on its outer circumference, a sleeve-shaped receiving part, and a connecting element connected to the receiving part with an inwardly directed, upwardly pivotable retaining edge that engages behind the retaining projection after pushing in the insert piece. A sleeve-shaped locking element surrounds the connecting element in a sliding manner and can be displaced between a release position, in which the axial sliding movement is transformed into an opening movement of the retaining edge(s) oriented transversally thereto, and a locking position, in which it surrounds the connecting element preventing upward bending in the region of the retaining edge(s) and the connecting element projects above the locking element, in an intermediate or coupling position of the locking element such that the retaining edge(s) can be bent upwards when the retaining projection on the insert piece is pushed in.

Abstract: A sanitary hose (1) has an inner hose (2) and a braided sheathing (4), made of mutually intersecting braiding parts (3), which encloses the inner hose (2). At least one of the braiding parts (3) or preferably all braiding parts (3) are configured here as single-part ribbons which thus replace multi-part braiding parts of such type formed by individual closely fitting wires or filaments. Here, a width of this ribbon is greater than its thickness and a wide side of the braiding parts (3) faces toward the inner hose (2). The peripheries (3a) of these ribbon-shaped braiding parts (3) have a tapered cross section, such that these peripheries (3a) extend tapering toward the outside and as a result permit an improved adaptation of intersecting braiding parts (3) even at the intersecting points (5).

Abstract: A hose coupling (1) is provided, having a sleeve-like configuration and, at at least one coupling end, has a connector (3) with a retaining profiling provided on the outer circumference of at least one connector sub-region, it being possible for a hose end (4) of a flexible hose (2) to be pushed onto said at least one profiled coupling end.
