ABSTRACT:
A portable signalling device is disclosed. The device comprises a housing having a longitudinal opening therein, a signal support slidably engaged in the longitudinal opening between a contracted position and an expanded position, and a clip on the housing. The signal support is capable of displaying a signal when the signal support is in the expanded condition. The clip is adjustable from a closed position, which secures the signal support in the contracted position and provides a slot suitable as a belt loop for securing the device on a belt or strap, to an open position allowing movement of the signal support to its expanded position and removal of the device from a closed belt or strap inserted through the slot.
