The drone (10) comprises a drone body (12) and a plurality of propulsion units (16) to drive propellers (18). Removable lateral bumpers (22) extend beyond the area of rotation of the propellers, each bumper being connected to the propulsion units on the same side by connection arms (24) each comprising a pair of elastically deformable elongated blades with at their end a clamp of mounting on a barrel (26) of the motor. Under the effect of an external transverse effort exerted in a median region, the two blades may be deformed in the direction of a mutual moving closer towards a mounting/dismounting position producing, by leverage, an opening of the clamp, so as to secure the bumper arm to the propulsion unit, and conversely the mounting/dismounting of the bumper by detachment of the clamp from the barrel, by the only transverse effort exerted on the connection arms.
