A suction cup for a tool driven by vacuum is presented, the suction cup in a first or upper end arranged to be brought into fluid flow communication with a vacuum source and in its opposite end arranged to be brought tightly into contact with the surface of an object to be handled. The suction cup is in its lower end arranged to be coupled to a sealing ring having a sealing surface arranged between an outer periphery and a through-opening defined by an inner periphery, and the sealing ring in the region of its inner periphery having a lip arranged to engage with the suction cup, to which purpose the suction cup in its lower end has a circumferentially running groove) in which the peripheral region and the lip of the sealing ring is insertable under form fitting engagement and in a radially overlapping relation between the groove and the lip in the region (r) of engagement.

1. A suction cup for a vacuum powered tool, the suction cup comprising: a first or upper end configured to be brought into fluid flow communication with a vacuum source;a second or lower end opposite the first end and configured to be brought tightly into contact with a surface of an object to be handled by the vacuum powered tool;a sealing ring comprising a means for coupling formed integrally therewith and running circumferentially about an inner periphery of the sealing ring;at least one bellows comprising a first means for coupling formed integrally therewith and running circumferentially about an inner periphery in an upper end of the bellows, and a second means for coupling formed integrally therewith and running circumferentially about an outer periphery in a lower end of the bellows; andan end piece comprising a means for coupling formed integrally therewith and running circumferentially about an outer periphery of the end piece,wherein the means for coupling of the sealing ring is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the end piece and the at least one bellows,the means for coupling of the end piece is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the at least one bellows and the sealing ring,each of the first and second means for coupling of one of the at least one bellows is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the end piece, the sealing ring, and another of the at least one bellows,the sealing ring, the at least one bellows, and the end piece form a set of connectable elements that are mutually connectable with one another, andeach one of the means for coupling has a complementary shape with respect to other ones of the means for coupling and forms an interface that is common for all connections between the mutually-connectable elements in the set. 2. The suction cup according to claim 1, wherein the sealing ring is a circular ring having a wall with a thickness reducing towards the outer periphery. 3. The suction cup according to claim 1, wherein each of the means for coupling comprises at least one of a circumferentially running groove defined between opposite upper and lower walls and having an outwardly mouthing cross-sectional profile with a mainly radial extension towards a bottom region of the groove located inside of a mouth, and a lip that is adapted to the groove for engagement with the bottom region of the groove, the lip being insertable in the groove under form fitting engagement and in a mutually radially overlapping relationship between the lip and the groove in the region of engagement. 4. The suction cup according to claim 3, wherein the groove has a widened bottom region, and the lip has a correspondingly shaped swelling. 5. The suction cup according to claim 4, wherein the bottom region of the groove has a semi-circular cross-section, and the lip has, at least partially, a toroidal shape. 6. The suction cup according to claim 5, wherein at least the lower wall of the groove has a heel extending into the groove and in the coupled position engaging a corresponding recess formed in the lower side of the lip. 7. The suction cup according to claim 4, wherein at least the lower wall of the groove has a heel extending into the groove and in the coupled position engaging a corresponding recess formed in the lower side of the lip. 8. The suction cup according to claim 3, wherein at least the lower wall of the groove has a heel extending into the groove and in the coupled position engaging a corresponding recess formed in the lower side of the lip. 9. A suction cup for a vacuum powered tool, the suction cup comprising: a first or upper end configured to be brought into fluid flow communication with a vacuum source;a second or lower end opposite the first end and configured to be brought tightly into contact with a surface of an object to be handled by the vacuum powered tool;a sealing ring comprising a coupling portion formed integrally therewith and running circumferentially about an inner periphery of the sealing ring;at least one bellows comprising a first coupling portion formed integrally therewith and running circumferentially about an inner periphery in an upper end of the bellows, and a second coupling portion formed integrally therewith and running circumferentially about an outer periphery in a lower end of the bellows; andan end piece comprising a coupling portion formed integrally therewith and running circumferentially about an outer periphery of the end piece,wherein the coupling portion of the sealing ring is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the coupling portion of the end piece and the at least one bellows,the coupling portion of the end piece is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the coupling portion of the at least one bellows and the sealing ring,each of the first and second coupling portions of one of the at least one bellows is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the coupling portions of the end piece, the sealing ring, and another of the at least one bellows,the sealing ring, the at least one bellows, and the end piece form a set of connectable elements that are mutually connectable with one another, andeach one of the coupling portions has a complementary shape with respect to other ones of the coupling portions and forms an interface that is common for all connections between the mutually-connectable elements in the set.
