The mechanism, adapted to lock the carrier against detachment from the frame, comprises a latch holding member (41) and a latch engaging member (42) for mounting on the carrier, and a resiliently biased latch (43) having first and second engaging protrusions (5, 6) for mounting on the frame. The latch (43) is rotatable relative to the frame between a locking position, in which the first engaging protrusion (5) engages releasably the latch engaging member (42), and a holding position, in which the second engaging protrusion (6) engages releasably the latch holding member (41). This enables the latch to be held in an unlocked state after it is disengaged, enabling the carrier to be removed without requiring further manual action. Respective such latches (43) are biased by integral resilient parts (8) in housings (21) on either side of the frame. |
