A door latch formed of transparent elastic plastic is disclosed. The latch has an elastic plastic band with a base segment adapted for mounting on a door and a catch segment flexibly attached to the base segment and extending angularly outward therefrom to project transversely beyond the base segment. The band also has a striker segment flexibly attached to the catch segment and extending angularly outward therefrom and transversely to a position outlying the base segment, and also a return portion flexibly attaching the striker segment to the base segment. The band is adapted to flexibly deform when pressed against a door jamb to selectively engage the jamb. The latch may also have a stiffening rib of plastic material rigidly affixed to the base segment within the band to act to restrict the deflection of the band when the band is pushed against a door jamb. This latch is useful as a transparent latch for a transparent display case.
