A device (1) covers the connection point (10) between two elongate, electrically conductive components (11, 12) in a moisture-tight manner. The device has a tubular sleeve (2) that surrounds the connection point (10). In the mounted position, a sealing element (3, 4) is attached to each of the two axial ends of the sleeve (2), which sealing element closes the sleeve (2) and lies tightly against the wall of the sleeve and has a feed-through (13, 14) for one of the electrically conductive components (11, 12), which feed-through is matched to the shape of the electrically conductive component (11, 12) in such a way that said electrically conductive component is tightly surrounded. In the mounted position, a cover (5, 6) that encompasses the sleeve and the sealing element (3, 4) located in the sleeve is attached to each of the ends of the sleeve (2), which cover has a feed-through (15, 16) for one of each of the electrically conductive components (11, 12). In the mounted position, the covers (5, 6) are attached to the sleeve (2) where each of the sealing elements (3, 4) is clamped between the cover (5, 6) and the sleeve (2).
