A locking means for halters comprises a clasp which is mounted in a strap included in the halter, usually the crownpiece. The clasp comprises a pin portion (2) and a sleeve portion (1). These two portions are provided with cooperating locking elements (7, 14) for releasably interconnecting the pin and sleeve portions. According to the invention, the locking means is also provided with a safety release device (5, 6, 13) which can be activated and deactivated by shifting the positions of the pin and sleeve portions (1, 2) relative to each other. The safety release device comprises a locking tongue (5) included in the pin portion (2), and a recess (12) formed in the sleeve portion (1) and adapted to receive the locking tongue. The locking tongue (5) has an enlarged tip (6), and the recess (12) is provided with at least one locking projection (13). The enlarged tip (6) of the locking tongue and the locking projection (13) together constitute a snap lock (6, 13). This is arranged to keep the pin and sleeve portions interconnected by yieldable action, until a separating force acting in the strap overcomes said yieldable action. In the deactivated position of the safety device, the pin and sleeve portions (1, 2) are interconnected at least by means of the locking elements (7, 14), and in the activated position thereof, the pin and sleeve portions are interconnected merely by means of the snap lock formed by the locking tongue (5) and the locking projection (13). |
