The lock is for closing an opening, and comprises a lock housing (10) which fills out the opening and at least one movable lock heel formation (13) for working in conjunction with the opening walls. The lock housing contains members (17, 25) for manoeuvring the lock heel formation between active and inactive lock positions. The one wall of the lock housing is provided with a hole through which the manoeuvring members are accessible. The hole is provided with an internal screw thread for screwing in a cover plug (31) of elastic material. The cover plug forms a first barrier between the manoeuvring members and the outside of the lock housing. The lock housing wall has tracks for retention of a sealing plate (33), which plate forms a second barrier between the cover plug and the outside of the lock housing. |
