Abstract: A telescopic support stand (1) comprises a telescopic column (2) extending along a longitudinal axis (X) and a supporting base (10) provided with a sleeve (15) intended to receive a base portion (3a) of the column (2) along which there is defined an opening bordered by an edge (15a) through which the column (2) is inserted into and extracted from the sleeve (15), the column (2) being provided with a coupling device (30) which can be moved between a coupling configuration (W) in which the column (2) is coupled with the sleeve (15) and a release configuration (W?) in which the column (2) is released from the sleeve (15), the coupling device (30) comprising an abutment element (31) which can move radially within the column (2) between the coupling configuration (W) in which an end portion (40) of the abutment element (31) projects radially from the column (2) and the release configuration (W?) in which the abutment element (31) is withdrawn towards the interior of the column (2), the end portion (40) and the edg
