A push-lock includes a body. The body is formed with a channel having a pair of portions. A cylinder is movable in the body between a front position and a rear position, and has a latch rotatably connected thereto. The latch defines two opposed cutouts in a periphery thereof. A clip has a pair of shanks resiliently flexible in the portions of the channel. The shanks normally abut the periphery of the latch. A spring is provided for moving the cylinder back to the front position. Additionally, the latch can be turned relative to the cylinder in such a manner that the shanks snapped in the cutout may be pushed outward by the turning latch till the shanks fully slide out of the cutouts and abut the periphery of the latch again.

1. A push-lock comprising: a body (10) having a front opening (11) and a rear opening (12) in communication with said front opening (11), said body (10) being formed with a channel (13, 13a) having a lateral portion laterally defined in the body (10) and at least one straight portion (131, 131a)
1. A push-lock comprising: a body (10) having a front opening (11) and a rear opening (12) in communication with said front opening (11), said body (10) being formed with a channel (13, 13a) having a lateral portion laterally defined in the body (10) and at least one straight portion (131, 131a) defined in a face defining the lateral portion and communicating with said rear opening (12) substantially tangentially; a cylinder (20) movable in said front opening (22) of said body (10) between a front position and a rear position, said cylinder (20) having a latch (21, 21a) rotatably connected thereto and extending backward through said rear opening (12), said latch (21, 21a) defining at least one cutout (22, 22a) in a periphery thereof; a clip (30, 30a) received in said channel (13, 13a) of said body (10) and having a lateral rod received in the lateral portion of the channel (13, 13a) and at least one shank (31, 31a) extending from the lateral rod and resiliently flexible in said straight portion (131, 131a) of said channel (13, 13a), said shank (31, 31a) normally abutting said periphery of said latch (21, 21a) but snapping into said cutout (22, 22a) and catching said latch (21, 21a) when said cylinder (20) is moved to said rear position; and a spring (40) for moving said cylinder (20) back to said front position; wherein said latch (21, 21a) can be turned relative to the cylinder (20) in such a manner that said at least one shank (31, 31a) snapped in said cutout (22, 22a) may be pushed outward by said turning latch (21, 21a) until said shank (31, 31a) fully slides out of said cutout (22, 22a) and abuts said periphery of said latch (21, 21a) again before said cylinder (20) will be moved back to said front position by action of said spring (40). 2. The push-lock as claimed in claim 1, wherein said body (10) has a longitudinal groove (14) defined therein, and wherein said cylinder (20) has a stud (50) extending into and movable along said longitudinal groove (14) of said body (10), thereby limiting the movement of said cylinder (20) in a range between said front position and said rear position. 3. The push-lock as claimed in claim 1, wherein said cylinder (20) is configured so that said latch (21, 21a) can only be turned relative to said cylinder (20) by turning a correct key inserted in said cylinder (20). 4. The push-lock as claimed in claim 1, wherein said clip (30) has a U-shaped configuration with a pair of shanks (31), and wherein said latch (21) defines two opposed cutouts (22) in said periphery thereof, said channel (13) of said body (10) is shaped to receive said clip (30) and has a pair of straight portions (131) allowing said shanks (31) to be resiliently flexible therein, thereby enabling said shanks (31) to normally abut said periphery of said latch (21) but to snap into said cutouts (22) and catch said latch (21) when said cylinder (20) is moved to said rear position. 5. The push-lock as claimed in claim 1, wherein said clip (30a) has an L-shaped configuration with one single shank (31a), and wherein said latch (21a) defines one cutout (22a) in said periphery thereof, said channel (13a) of said body (10) is shaped to receive said clip (30a) and has one straight portion (131a) allowing said single shank (31a) to be resiliently flexible therein, thereby enabling said single shank (31a) to normally abut said periphery of said latch (21a) but to snap into said cutout (22a) and catch said latch (21a) when said cylinder (20) is moved to said rear position.
