A telescopic lance, comprising a lance handle (5) with a fixed inner pipe (3), an extractable outer pipe (4) and at least one locking mechanism (10,20), wherein the extractable outer pipe (4) is located outside, and slidably longitudinally arranged with the fixed inner pipe (3), and said locking mechanism (10,20) is arranged to allow motion of the extractable outer pipe (4) with respect to the fixed inner pipe (3). A first locking mechanism (20) comprises a protrusion (21) for engagement with a locking slot (22), wherein twisting of the extractable outer pipe (4) brings the protrusion (21) into or out of engagement with the locking slot (22), and a second locking mechanism (10) comprises a spring loaded lock handle (13) with a through going aperture (15) for trapping and releasing the extractable outer pipe (4). The invention also relates to a combination of a telescopic lance and a trigger gun (8) for use with a high pressure washer.
