    • A linear actuator (1) comprising an electric motor (20) connected to a transmission (40), a spindle (80) connected to the transmission (40), a spindle nut (81) arranged on the spindle (80), an outer tube (3) being connected to the housing (10), an inner tube (2) being connected to the spindle nut (81), the spindle nut (81) and the inner tube (2) being guided inside the outer tube (3). A sealing element (50) is arranged between the outer tube (3) and the housing (10). A retaining element (60) is connected to the housing (10) and configured for retaining the sealing element (50) relative to the housing (10). The retaining element (60) includes a base (b) with a peripheral wall (66) surrounding the housing (10) and having a base (b) and a protruding part (62) opposite the base (b). The protruding part (62) includes a first peripheral face (f 1 ) constituting a first contact surface for engaging the sealing element (50). The outer tube (3) has a second peripheral face (f 2 ) constituting a second contact surface for engaging the sealing element (50). The housing (10) has a third peripheral face (f 3 ) constituting a third contact surface for engaging the sealing element (50).
