Abstract: Tubular actuator (1) for driving a windable element in a building, comprising: in a tube (3) having a longitudinal axis (X-X?), a reduction gear and an output shaft (4) at a first end of the tube and a fixed-point (2) in two portions at a second end of the tube, the fixed-point comprising a first portion (20; 20?) at least partially outside the tube and a second portion (40; 40?) assembled in the tube, wherein the first portion comprises at least one torque and weight-bearing axial extension, this torque and weight-bearing axial extension being capable of being inserted into at least one recess of the second portion and being locked in translation along the longitudinal axis relative to the tube of the actuator by a first locking means (35, 37, 38).
