The present invention provides a power tool comprising: at least a pair of handles (10, 20), wherein each of the pair of handles has (a) a respective actuator (14, 24) for operating said power tool; and (b) a respective guard member (16, 26) for restricting access to said respective actuator; the power tool further comprising a 5 latch mechanism (72, 74) for latching the pair of handles (10, 20) together, wherein the latch mechanism has a first component (72) mounted on a first one (16) of said guard members and a second component (74) mounted on a second one (26) of said guard members and adapted to engage with said first component (72). Thus, the components of the latch mechanism are mounted on the respective guard members 10 for the actuators, rather than directly on the handles themselves. This ensures that the components of the latch mechanism are able to latch the handles together without being impeded by the presence of the guard members or the actuators. In a preferred embodiment of the invention, the latch mechanism further comprises user operable means (72a, 72f) for holding the latch mechanism both in a latched 15 condition and in an unlatched condition but not otherwise, such that the latch mechanism has only a first stable configuration which is the latched condition and a second stable configuration which is the unlatched condition. This ensures that the handles can be latched together as desired by the user, but without becoming latched together accidentally at unwanted times or alternatively becoming unlatched 20 accidentally.
