ABSTRACT:
A linear drive without a piston rod, which has a laterally slotted guide tube closed on the end faces and a piston mounted so as to be slidably displaceable therein, is provided with a sealing band and with separate profile elements engaging the sealing band. The sealing band extends from one end of the guide tube along its longitudinal slot to its other end. In order to hold the sealing band in the longitudinal slot, separate profile elements are arranged in the longitudinal slot. The profile elements cause the sealing band to engage the guide tube.
