1. A connecting device (100) for connecting a first and a second tube, the connecting device (100) comprising a sealing sleeve (200), a plurality of support elements (300) and at least two clamping bands (401, 402), wherein in order to form the connection, a first of two end portions (201, 202) of the sealing sleeve (200) receives a tube end portion of the first tube and the second end portion (202) receives a tube end portion of the second tube, which are connected to each other by means of the sealing sleeve (200), wherein the sealing sleeve (200) has an inner side (210) and an outer side (220), and wherein the plurality of support elements (300) are arranged along the outer side (220) of the sealing sleeve (200) without being connected to each other, and wherein each support element (300) at least partly consists of or contains a deformable material, and wherein each support element (300) has a first support element contact pressing portion (310) and a second support element contact pressing portion (320), and wherein the first support element contact pressing portions (310) are arranged one following the other along a circumference of a first circle (230) along the outer side (220) of the sealing sleeve (200) and form a first support element end portion (330) having a first opening for receiving the first end portion (201) of the sealing sleeve (200), and wherein the second support element contact pressing portions (320) are arranged one following the other along a circumference of a second circle (240) along the outer side (220) of the sealing sleeve (200) and form a second support element end portion (340) having a second opening for receiving the second end portion (202) of the sealing sleeve (200), and wherein at least one first support element contact pressing portion (310) is connected to a second support element contact pressing portion (320) by means of at least one deformable connecting portion (380), wherein by means of shortening or extending of the clamping bands (401, 402), which are in the form of a first clamping band (401) and a second clamping band (402), and wherein the first clamping band (401) is associated with the first support element contact pressing portion (310) and the second clamping band (402) is associated with the second support element contact pressing portion (320) and the first support element contact pressing portions (310) are positioned closer to or farther from each other along the circumference of the first circle (230) along the outer side (220) of the sealing sleeve (200) and thus compress or relax the first end portion (201) of the sealing sleeve (200), and the second support element contact pressing portions (320) are positioned closer to or farther from each other along the circumference of the second circle (240) along the outer side (220) of the sealing sleeve (200) and thus compress or relax the second end portion (202) of the sealing sleeve (200).
