A tool (2,20) inserted into first plastic tube (1) in first direction (ER1) maintains internal cross-section of plastic capillary tube(s) (4) to be connected to first tube in a direction (ER2) at right angles to it. An extractor tool (6) for removing tool spigots (20) from capillary tubes applies a force onto the tool (2) in the opposite direction to the spigot insertion direction (ER2). The tool extractor(6) is inserted between the inner wall of the first tube(1) and a tool(2) to be removed. Two or more rods(7) of the extractor are inserted between the tool and first tube(1) so that the spigots(20) lie between the rods. The rods are held in a common holder and a movable spacer slides along the rods to maintain a gap between them. Extractor rods have wedge-shaped ends to ease insertion between the first plastic tube and the tool. Spigot spacing corresponds to the distance between tubes. Each spigot has a length equal to at least one and a half times the thickness of the first plastic tube. Part of the tool is flexible and made of spring steel while areas around the spigots are rigid. A stop(5) at one end of the tool defines the tool position particularly in relation to its angle and/or its horizontal position. A support(3) is inserted into the first tube to retain the tool position. An independent claim is included for a process for joining plastic tubes to produce capillary mats which involves: a) insertion of a tool(2) into the first plastic tube(1) in a first direction(ER1); b) insertion of one or more spigots(20) of the tool into capillary tubes perpendicular to the first tube; c) connecting the capillary tubes to the first tube, preferably by welding; d) applying a force with a tool extractor to slide the spigots out(ER2) of each capillary tube. Die Erfindung betrifft ein Montagesystem zur Verbindung eines ersten Kunststoffrohres (1) mit mindestens einem zweiten Kunststoffrohr (4), insbesondere zur Herstellung von Kapillarrohrmatten, mit einem in einer ersten Einführrichtung (ER1) im Wesentlichen axial in das erste Kunststoffrohr (1) einführbaren Formwerkzeug (2, 20), das zur Aufrechterhaltung des Innenquerschnitts eines mit dem ersten Kunststoffrohr (1) zu verbindenden Verbindungsbereichs eines zweiten Kunststoffrohres (4) in einer im Wesentlichen senkrecht zur ersten Einführrichtung (ER1) liegenden zweiten Einführrichtung (ER2) zumindest teilweise in das zweite Kunststoffrohr (4) einführbar ist. Es ist mindestens ein Entfernungsmittel (6) zur Entfernung eines Formwerkzeugs (20) aus mindestens einem zweiten Kunststoffrohr (4) durch Aufbringen einer auf das Formwerkzeug (2) wirkenden Kraft in einer im Wesentlichen entgegen der zweiten Einführrichtung (ER2) liegenden Richtung vorgesehen. Es wird so ein Montagesystem zur Verbindung von Kunststoffrohren angegeben, mit dem die Herstellung von Kapillarrohrmatten verbessert wird.
