1. A vacuum gripping element (1), which is configured to suck or hold a component to be transported when subjected to a vacuum, comprising
a base body (2) with at least one vacuum supply channel (3),
an elastic, form-flexible sealing element (4), which is connected to the base body (2) and is provided for sealing contact with the component to be transported,
a first fastening means (5) on the base body (2) for fastening the vacuum gripping element (1) on a carrying device (6), wherein the base body (2) and the sealing element (4) are arranged along a main axis (7) of the vacuum gripping element (1), wherein the first fastening means (5) is formed by a locking coupling (8) for positively connecting and releasing the vacuum gripping element (1) relative to the carrying device (6) as required,
or wherein the base body (2) comprises a first base body part (30) and a second base body part (31), said first base body part (30) being provided for positively connecting and releasing relative to the carrying device (6) as required by means of the first fastening means (5), and said second base body part (31) being connected to the elastic, form-flexible sealing element (4), and wherein a second fastening means (32) for positively connecting and releasing the first base body part (30) relative to the second base body part (31) is formed by a locking coupling (8), and
wherein the base body (2) comprises a hollow-cylindrical fastening section (9) in which the locking coupling (8, 8′) is formed, and
wherein the locking coupling (8, 8′) comprises an actuator element (10), a spring element (11) and at least one locking element (12), wherein the spring element (11) urges the actuator element (10) into an end position, and wherein the at least one locking element (12) is urged into a locking position by the actuator element (10), wherein the actuator element (10) is arranged within the hollow-cylindrical fastening section (9) and is mounted so as to be adjustable along the main axis (7), and wherein the actuator element (10) comprises an actuating surface (17) which is provided for the application of pressure starting out from a constructionally separate, pin-shaped actuating tool (18).
