The normal wall thickness 8 remains here through becomes a very stable and therefore moist connection brackets of this type. The reinforcement 5 created tight connection bracket. Dar des edge bead 3 near the building extends over Beyond that, the sight of the tie-down brackets becomes the vertex 6 to a point that on mer improved, since the grooves for receiving the 5 a through the middle of this bead 3 is he sealing material from the outside no longer to s "hcn stretching, less than 45 to the vertical inclined servants, raden lies.

Claims

Patent claims:

1. Device for tightly connecting the ends of two juxtaposed gutter sections made of plastic, each having an outwardly bent edge bead on their longitudinal edge remote from the building and one edge bead bent into the interior of the gutter sections on their longitudinal edge near the building, consisting of one on the outside of the ends the gutter sections snugly fitting connection clip made of plastic, which on their remote L; ^; ngsrand has an edge bead that can be pushed into the edge bead of the gutter sections away from the building and, on its longitudinal edge near the building, a bead over the edge bead of the gutter sections near the building, characterized in that the connecting clip (1) consists of a particularly impact-resistant polyvinyl chloride clip (first, the connecting clip) ) is reinforced on its outside and on the outside of its edge bulge (3) close to the building in such a way that its wall thickness increases symmetrically from the center to its two ends, and that the two edge bulges (2 and 3) of the connecting bracket (I. ) protrude beyond their ends.

2. Connecting clamp according to claim 1, with provided in the region of its two ends for receiving a sealing material, perpendicular to the longitudinal direction of the gutter, grooves, characterized in that the wall thickness of the connecting clamp (1) from its center to the two grooves (4) in the way increases linearly that the connecting bracket (1) in the area of the groove base has approximately the usual wall thickness (8) present in its center, and that the wall thickness of the Verbiiulungsklamnier (1) remains the same from the grooves (4) to the ends.

3. connecting clamp according to claim I or 2, characterized in that the outside Reinforcement (S) of the edge bead (3) near the building extends over its apex (6) extends to a point on a through the center of this edge bead (3) extending, is below 45 straight lines inclined to the perpendicular.

4. connecting clip n; I one of claims 1 to 3, characterized in that their bulge ends one over the inside of the clamp and one over the edge bead away from the building (2) have extending chamfer (7).

Ends of the gutter sections snugly fitting connecting clip made of plastic, which is attached to her Longitudinal edge remote from the building can be pushed into the edge bead of the gutter sections remote from the building Beaded edge and on its longitudinal edge close to the building one of the beaded edge of the gutter sections close to the building having overlapping bead.

In a known connection of this type (German utility model 1 936 685), the connecting bracket a relatively low rigidity, which is particularly evident in the building Edge bead of the connecting clip has a detrimental effect. This is because of its low Restoring force after snapping over the edge bead of the gutter sections near the building relatively slightly bent upwards, which no longer ensures a sufficient seal is. A plastic must also be used for the manufacture of these known connecting blocks be used which have sufficient rigidity at normal temperature of about 20 "C. However, this has the consequence that the plastic does not have sufficient impact strength at lower temperatures has more to deal with impact stresses, such as B. Bumps when hiring a ladder, to survive without material damage. The known The connecting clamps even tear during assembly.

The object of the invention is thus to provide a connecting bracket of the type in question Art to be trained in such a way that they still have a firm and permanent connection even at temperatures below 0 ° C of the gutter sections guaranteed.

This object is achieved according to the invention in that the connecting clip consists of a particularly impact-resistant polyvinyl chloride that the connecting bracket on its outside and on the Outside of their edge bead near the building is reinforced in such a way that their wall thickness of the Middle / u increases symmetrically towards both ends, and that the two edge beads of the connecting bracket protrude beyond their ends.

Due to this special Waiid strength distribution that a firm pressing of the connecting clamp on the gutter sections guaranteed and still allows manual assembly of the connecting bracket, its manufacture can be a highly elastic Polyvinyl chloride can be used, that is, temperatures still have sufficient impact strength has, so that even at these temperatures a firm and permanent connection of the gutter section is guaranteed. For example, a polyvinyl chloride with a high impact strength is used at 0 C of up to 30 kp cm / cm- 'and a modulus of elasticity from ISOOO to
