A plastic arrangement that includes a first plastic component, a second plastic component, and a plastic lock mechanism for fastening the second plastic component to the first plastic component. The plastic lock mechanism includes a first lock unit and a second lock unit. The first lock unit includes a U-shaped cantilever member, a catch element and a catch element retention part. The second lock unit includes a protruding member and a protruding member retention part. The plastic lock mechanism provides a locked position wherein the catch element retention part restricts movement of the catch element for preventing the second plastic component from separating from the first plastic component, and the protruding member retention part restricts movement of the protruding member for hindering the moving of the first lock unit to a released position.

An all-plastic, tumbler-free cam lock includes a cylindrical lock body with a flange extending radially from the distal end to be glued to a surface surrounding a mounting hole. The lock body has a bore extending axially and a central spindle received coaxially in the bore. A key has a cylindrical tubular key body insertable concentrically between the lock body shoulder and the distal end of the spindle. A pair of outer key lugs extend radially outwardly from the tubular key body to pass through the key channels of an interior shoulder of the lock body, thus permitting access only by one key configuration. A third key lug extends radially inwardly from the inner surface of the tubular key body to engage a keyway channel of the spindle.

A disposable, flexible locking restraint having a base and first and second straps integrally molded of a dry flexible plastic is provided. During use, toothed portion of the straps engage toothed portions of associated pawls to provide for unidirectional travel of the straps through the base. For increased security, pawl locks are provided on the base. Each pawl lock has first and second retainers to engage the pawl lock on the base, where the first retainer is spaced from the second retainer along a length of the pawl lock. When the first retainer retains the pawl locks in the base, the pawls have sufficient freedom of movement to allow unidirectional movement of the straps through the base, and when the pawl locks are depressed such that the second retainer retains each pawl lock in its respective lock aperture, the pawl lock engages the pawl and presses the pawl against the strap, preventing further travel of the strap.

A child safety door latch system includes interchangeable pushbutton compression springs of varying tensions proportional to selected values of thumb opposition strength. A pair is selected for a predetermined age group. A pair of handles each contain one of the selected pair of compression springs and a pushbutton. A latch includes a latch compression spring and a latch slider. A master connector is coupled to the latch slider. In a locked mode, the selected pair of compression springs cooperate with the latch compression spring such that the latch protrudes from the latch sleeve, holding the door locked.
