1. A padlock for connecting two members (M, M'), in particular two end members of a chain, comprising a lock body (2) which has an external tubular strengthening casing (1) of a material which is more resistant than the lock body, and two openings (3, 3') which are open at the periphery, for accommodating respective members (M, M') of the chain, and two mounting bores (5, 5') which each extend transversely with respect to a respective one of said openings (3, 3'), wherein a lock cylinder (7) which is actuable by means of a key and which is in parallel-axis relationship to the mounting bores (5, 5') is fitted in the lock body (2) and mounted longitudinally displaceably in each mounting bore (5, 5') is a straight bolt member (4, 4') which in the extended open position leaves the associated opening (3, 3') in the lock body (2) open and which in the retracted closed position passes through said opening (3, 3'), in that position engages through the member (M, M') of the chain which is fitted therein, and can be secured in position by a blocking member (9-109, 9'-109') which is controlled by the lock cylinder (7) and which is mounted in the lock body (2) movably away from and towards the bolt member (4, 4') and which engages into a peripheral groove (12, 12') in the bolt member (4, 4'), characterised in that the two bolt members (4, 4') and the corresponding mounting bores (5, 5') of the lock body (2) are arranged on opposite sides of the lock cylinder (7) and the associated openings (3, 3') for receiving the members (M, M') of the chain are provided in the respective end surfaces of the lock body (2), and that the external tubular strengthening casing (1) is directed with its longitudinal axis transversely with respect to the bolt members (4, 4') and the lock cylinder (7) and is provided with a respective lateral through opening (105, 105', 8) in the region of each of the bolt members (4, 4') and the key opening (207) of the lock cylinder (7). |
