Abstract

A lock (10) for an access cover (12) comprises a bolt (13) and housing (14), the bolt can move in a first direction in the housing, and in a second direction between an advanced position in which it protrudes from the housing via a bolt aperture and a further, relatively retracted position. The housing includes a restraint (28, 42, figure 8) with which the bolt is engageable so as to limit movement of the bolt in the second direction; and the lock includes a biasser (27, figure 2) that biases the bolt into the restraint. The housing includes a key aperture (44, figure 5) for receiving a key (29, figure 3) that is engageable with the bolt such that movement of the key is capable of moving the bolt in the first direction against the action of the biasing means and out of engagement with the restraint; and in the second direction between the advanced and further positions.
