Abstract
A lock includes a shackle having a short first portion, a long second portion and a curved portion. The second portion has a groove defined in outside thereof. A body has a first hole and a second hole for receiving the first and second portions respectively. A passage is defined in outside of the body and perpendicularly communicates with the second hole. A positioning unit is located in the passage and has a securing member, a pin and a resilient member. The securing member has a path in which a narrowed section of the pin is inserted. The resilient member biases the pin which is engaged with the groove. When the pin is moved to compress the resilient member, the pin is removed from the groove and the narrowed section is located corresponding to the groove so that the second portion can be removed from the second hole.
