1. A vacuum holding device for attaching objects to an essentially gas-tight contact surface, comprising: a holding body that forms a vacuum chamber, wherein a vacuum is producible in the vacuum chamber following application to the contact surface, and the holding body comprises a press-on web with a web front edge encircling the vacuum chamber, wherein the web front edge is oriented towards the contact surface,at least one seal, that seals the vacuum chamber towards an exterior of the holding device in a gas-tight manner against the contact surface,at least one opening between the vacuum chamber and the exterior having at least one valve that ensures gas-tight opening and closing between the vacuum chamber and the exterior,whereinthe holding body with the press-on web, during formation of the vacuum in the vacuum chamber, presses on the contact surface by means of the seal provided towards the contact surface,the seal comprises one or several U-profiles, wherein two limbs and a foot surface linking the limbs form an U-profile and the limbs at least partially bilaterally encompass the respective press-on web of the holding body and the foot surface spans the respective web front edge of the press-on web, wherein the web front edge has a sealing effect on the foot surface of the seal under the vacuum in the direction of the contact surface andthe holding body, in addition to the press-on web comprises a downwards projecting peripheral web, the peripheral web encircles the press-on web and a groove is formed between the press-on web and the peripheral web, in which a limb of the seal engages. 2. The vacuum holding device according to claim 1, wherein the holding body, in addition to the press-on web and the peripheral web furthermore comprises in the direction of the vacuum chamber a downwards projecting chamber web, the chamber web encircles the press-on web towards the inside of the vacuum chamber and a second groove is formed between the press-on web and the chamber web, so that two grooves are formed, one groove between the press-on web and the peripheral web and one grove between the press-on web and the chamber web, in which the limbs of the seal engage. 3. The vacuum holding device according to claim 2, wherein two concentric encircling seals which are U-shaped in profile are provided having limbs, the limbs of which engage in the grooves. 4. The vacuum holding device according to claim 1 or 2, wherein the limbs without contact pressure of the holding body on the contact surface have a play of movement in the groove or grooves and in the presence of contact pressure on the contact surface thicken via a compression effect of the seal such that the limbs only press against the side walls of the peripheral and the press-on webs and on the side walk(s) of chamber web, if present that form the grooves in case of contact pressure, creating an additional seal. 5. The vacuum holding device according to claim 1, wherein the valve is essentially designed as cylindrical, conical, spherical or hemispherical in shape. 6. The vacuum holding device according to claim 1, wherein the connection between the vacuum chamber and the exterior comprises a cylindrical, conical, spherical or hemispherical contact surface for receiving the valve. 7. The vacuum holding device according to claim 1, wherein the valve consists of a valve seat and an elastic rubber material at least in an area(s) that is in contact with the valve seat. 8. The vacuum holding device according to claim 1, wherein the valve comprises a valve seat and extends at one end in the manner of a band or a rod-like outlet with a resistance, particularly in the form of at least one crossbar or wedge, wherein the band or rod-shaped extension of the valve is held tight in the valve seat when vacuum is exerted from outside. 9. The vacuum holding device according to claim 8, wherein the band or rod-like outlet of the valve is elastic, particularly in order to keep the valve seat under elastic pretension. 10. The vacuum holding device according to claim 1, wherein the vacuum holding device comprises a retaining receptacle for the device mounting. 11. The vacuum holding device according to claim 1, wherein at least subareas between the peripheral web and the press-on web and the seal are equipped with a repositionable adhesive compound or the repositionable compound is introduced between the peripheral and the press-on webs and the seal. 12. A two-part set comprising the vacuum holding device according to claim 1 and an intermittently connectable and detachable device, gas-tight with the opening of the vacuum chamber towards the exterior, for generating a vacuum in the vacuum chamber. 13. The set according to claim 12, wherein the device for generating the vacuum is a vacuum pump with a relief valve. 14. The set according to claim 13, wherein the device for generating the vacuum is a piston suction pump. 15. The set according to claim 12, wherein the device for generating the vacuum is a piston suction tube with a suction tube and a suction piston but without a relief valve, wherein the piston suction tube comprises a suction tube opening at one end of the tube that provides a suction path and the suction tube is connectable by an, attachment to the opening of the vacuum chamber towards the exterior in a gas-tight manner and at an end of the suction tube opposite the suction tube opening an opposite end suction tube opening that is passable by the suction piston, so that in when the suction pistons is passing through the opposite end suction tube opening, ambient air is drawn into the suction path. 16.
