A device with which detachably to lock two elements to each other, said elements when not locked being telescopically displaceable relative to each other. The device comprises an insert (3), which may be entered into the outer element (1) and locked therein, and which comprises at least two sections (8, 9), each of said sections extending circumferentially along at least more than half the circumference of the inside of said outer element. Between the two sections the insert is provided with on the one side of the inner element (2) a distance piece (10) and on the other side thereof a cut (13). The insert is provided with a through conduit for the inner element (2) which is to be displaceable telescopically and lockable with respect to the outer element (1). In the area of said distance piece, the insert is provided with a larger inner radius or diameter than in the area of said sections. A locking element (4) is placed in the clearance between the outer and the inner elements, and means (5, 6) are provided by which to press the locking element against the inner element by pressing the locking element radially inwards from the outside, thereby clamping said element between on the one hand the inside of the locking element and on the other side the insides of the two sections. |
