Embodiment Construction

[0061] figure 1 The connectors shown in , 4 and 5 are used to connect two fluid conduits in the figure 2 and 3 The end pieces 1 and 2 shown in FIG. 1 are each provided with a surrounding retaining rib 3 or 4, which is fastened to one of the end sections 1 and 2 or formed in one piece with it. At least one of the two fluid lines can be constructed separately or as part of the fluid line arrangement, whereby one of the end sections 1 and 2 can also serve as a connection for such a fluid line arrangement.

[0062] The connecting device has a sleeve 5 made of fiber-reinforced or unreinforced thermoplastic. By plastic is meant at least one of the following materials: PA, PPS, POM, PP, PE, PET, PBT, PEN and PBN. As an alternative, the sleeve 5 can also be a thermosetting plastic such as phenolic resin.

[0063] The sleeve 5 is closed all around up to a slot 6 which extends axially over the largest part of the length of the sleeve 5 . In this case, one edge of the slot has a so...

Abstract

The system for connecting two pipes (1, 2) coaxially comprises triangular peripheral ribs (3, 4) on the ends of the pipes, between which a sleeve (5) fits. This has a slot which allows it to bend radially. Flanges (10) on the ends of the sleeve fit into grooves (3a, 4a) behind the ribs.

Description

technical field [0001] The invention relates to a connection device with coaxial end sections of two fluid lines to be connected, each of which is provided with a surrounding retaining rib, the connection device being provided with a sleeve , the sleeve has: an axial slot; a flexible hinge opposite the slot; and a retainer on its inside for snapping the retaining rib into the groove behind the retaining rib In this case, the joint can flex so elastically that it can exert a radial force on the part of the bushing adjacent to the slot against each other. [0002] According to this connecting device, the sleeve, with its slot widened, is radially placed on the retaining web of the end section. However, the end section cannot be inserted axially into the bushing like a plug-in type, because in this case one of the holders designed as a flange on the bushing end is so axially locked in a retaining Move in the groove behind the rib until another gripper abuts on the retaining rib...
