A locking device for securing a first structure to a second structure. The locking device comprises a housing securable to the first structure, a lock base securable to the second structure, and a locking tab slidably received within said housing. The locking tab has an extended position where a second end is slidably received within the lock base. The lock base has a flexibly resilient locking arm. When in its locked configuration the locking arm releasably engaged with the second end of the locking tab to prevent retraction of the tab from the lock base. The lock base has a resilient member biasing the locking arm to its locked configuration. The lock base has a flexibly resilient removable key member. When engaged with the lock base, a compressive force applied to the key member causes movement of the locking arm from its locked to its unlocked configuration.

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.

A fluid filtering cartridge comprising a filter element, including a body of filtering media and having a substantially hollow interior in fluid communication with an opening extending through the filtering media, and a sealing element situated in the opening. The sealing element presents a fluid-tight seal between the opening and a conduit received therein. The sealing element comprises a radially inwardly directed flange having an inwardly disposed edge with a ring member secured thereto. The ring member has an interior face sealingly received about the exterior surface of the conduit when the conduit is received within the opening through the filtering media to present a fluid-tight seal between the exterior surface of the conduit and the interior surface of the opening.

A filter cartridge for use with a filter head assembly and for filtering a stream of pressurized fluid. The filter cartridge comprises a housing enclosing filtering media, a retainer to releasably engage a receiver in a filter head assembly, and one or more rotationally engagable locks securing the filter cartridge to the filter head assembly upon the rotational engagement of the filter cartridge with the filter head assembly. The housing includes an upper end having therein entry and exit passages to permit fluid to enter the housing, pass through the filtering media and exit the housing. Rotational engagement of the filter cartridge with the filter head assembly causes the retainer and said the receiver to releasably secure the filter cartridge to the filter head assembly and to thereby permit fluid to travel from the filter head assembly through the entry passage and to permit fluid to pass from the exit passage into the filter head assembly. The locks help to resist the rotational disengagement of the filter cartridge from the filter head assembly.

A vandal-resistant frame has a rear member securable to a relatively vertical supporting surface and a front member hinged to the rear member for movement between open and closed positions. The front member has an aperture through which advertising, photographic or like material within the frame can be seen from an external position. The front member is secured to the rear member in a closed position by at least one projection on one member engaged in a recess in the other member adjacent to the aperture in the front member, whereby the projection or projections can be detached from the recess or recesses to open the frame by an appropriately shaped key member inserted between the front and rear members from a position within the aperture.
