A tube arrangement, comprising a tube made of a polymer material which is provided with an embedded reinforcement. At least one tube end is slid onto a short metal or plastic pipe. A pipe clamp, especially a screw pipe clamp, secures the tube end onto the pipe. A retaining sleeve on the tube end secures the pipe clamp to the tube. This retaining sleeve is made of a polymer material and comprises a one piece molded part which is pushed onto the tube end. The retaining sleeve comprises the following components: a retainer ring with an inner diameter which is positioned over the outer diameter of the tube end; a clamp receiving element in the form of at least two axially extending retaining elements which are connected to the retainer ring at one end; a retaining collar at the other end of each retaining element; and a collar ring with an inside diameter connecting the retaining collars.

Tube arrangement

A T-shaped hose includes a vulcanized main hose having a wall with an opening therein and a vulcanized branch hose having one end disposed adjacent to the opening in the main hose, so that the hoses are approximately in the form of a 'T'. A hollow generally cylindrical branch sleeve having a generally outwardly directed flange at its lower end and an annular recess formed in the outer wall of the sleeve adjacent to the flange, is disposed primarily within the branch hose with the flange engaging the inner wall of the main hose and defining therebetween an annular channel. A fixation member composed of a vulcanizable rubber is received with the recess and channel.

T-shaped hose

The invention relates to a mold for producing a T-shaped hose composed of a main hose having a sidewall with an opening and a secondary hose joined at one end to the sidewall opening of the main hose to form a 'T'. The mold includes a main mandrel for the main hose having a disk-shaped recess on which the main hose is mountable with its opening in registry with the mandrel recess and a secondary mandrel for the secondary hose having a cylindrical recess adjacent to one end thereof. The secondary mandrel is disengageably secured at the one end thereof to the main mandrel adjacent to the recess thereof, so that the mandrels are arranged in the form of a 'T' and cooperate with one another to define an interior mold cavity at the zone of connection. The mold further includes an outer mold part that is mountable on the main hose and the secondary hose after each has been mounted on its respective mandrel parts. The outer mold part then surrounds the hoses in the zone of connection to define between the hoses and itself an exterior mold cavity.
