Abstract: A fastening for securing an apparatus, such as a pager or a mobile telephone, to a belt is disclosed. The fastening includes a body, a board and a flexure strip attached to the apparatus. The body defines a recess in a front portion thereof for receiving the flexure strip and has a plurality of ratchet teeth uniformly distributed at two opposed sides of a rear portion thereof. The board is movably received in the rear portion of the body and has pawls integrally formed thereon for engaging with respective pair of the ratchet teeth. The pawls has a press bar integrally formed therebetween and a hook is integrally formed at a rear end of the board for abutting the belt. By this arrangement, a space is defined between the board and the back of the apparatus, which can be adjusted and adapted for receiving different belts with various widths. Also, the direction of each ratchet tooth is configured to enable the board to move only toward the front portion of the body so that the belt can be securely gripped.

Abstract: A mobile telephone fastening includes a cramping member and a gripping member. The cramping member has a base attached to a back of the mobile telephone and a buckle integrally extending from the base. The buckle has two opposed long edges and two opposed short edges. The gripping member includes an enclosure with a longitudinal recess, a press button received in the enclosure, a swing plate pivotedly engage with the enclosure, and an inverted-U-shaped flexure strip. The longitudinal recess has a circular space defined at a lower portion thereof. The swing plate has a protrusion extending into the longitudinal recess of the enclosure. In operation, the two opposed short edges of the buckle can be inserted into the recess and urge the protrusion of the swing plate to retract. When the buckle reaches the circular space of the recess and force applied on the protrusion by the buckle is removed, the protrusion will restore to project beyond the enclosure.

Abstract: A fixing apparatus for a portable telephone includes an engaging device connected to the portable telephone, a socket for detachably receiving the engaging device, and a cramp connected to the socket for fixing itself and the socket on an objective body such as a belt. The engaging device is allowed to slide in the socket and may be manually made to turn substantially ninety-degrees in the socket thereby being located in place in the socket. When the engaging device is located in place in the socket, it may be manually made to turn ninety-degrees in the socket and may be manually pulled to slide out from the socket.
