<p>In a pick-up having a base unit (10) and an exchangeable front part (12), which has two axially slidable locking pins (16) which can elastically yieldably engage recesses (23) in the base unit, the locking pins form pivot pins for a visor (15) pivotally mounted on the front part, and the locking pins and the part have cooperating cam means (19, 21) which convert pivotal movement of the locking pins to axial movement, so that the locking pins may be engaged with and be disengaged from the recesses (23) of the base unit. The movements of the visor are thus used for locking and releasing the front part.</p> |
