A latch for a sliding frame may be provided with a mounting end for mounting the latch on a mounting surface over which a sliding frame would travel along a sliding path, and a resilient blocking element having an end portion and a body portion coupled to the mounting end, and a stop element positioned to engage the end portion of the resilient blocking element and adapted to prevent the sliding frame from opening when the frame is in a closed position. A user may disengage the latch by removing the resilient blocking element from the sliding path so that the sliding frame can be moved to an open position.
