A safety lock is disclosed and comprises a body, a bolt and a handle. The body is securable to one member. The bolt is mounted to the body for reciprocation between projecting and retracted positions. In the projecting position, a bolt end portion protrudes beyond the body and is engageable in another member, to prevent relative movement of the members. In the retracted position, the end portion is incapable of engagement in the other member, to permit said relative movement. The handle is releasably engageable to the bolt. The handle, body and bolt are adapted such that when the handle is engaged to the bolt, the handle permits manual reciprocation of the bolt, and are further adapted such that when the handle is disengaged from the bolt and the bolt end portion is inaccessible for manual manipulation, the bolt is inaccessible for said manual reciprocation.
