<p>Snap lock comprising two lock parts (1, 2), where a first lock part (1) has a slotted sleeve (4) provided with a constriction (16) which when being pressed out is mountable on a second lock part (2) over a front end section (8) thereof, wherein said sleeve (4) firstly is put in a pressed out position before the sleeve (4) at reached locking position is kept blocked against being taken off by cooperation between constriction and a thickening (10) arranged on the front end section (8) of the second lock part (2). A friction means (21) is arranged in the area between contact surfaces of the second lock part (2) and the sleeve (4) so that the contact pressure on the friction means (21) is varying when switching the constriction between the locking position and the pressed out position, wherein the friction means when affected by the snap effect is brought to elastic deformation between the contact surfaces in the locking position to prevent turning.</p> |
