VALVE GUARD ASSEMBLY

摘要

A valve guard assembly for a gas cylinder has a mounting collar (2), which is adapted to fit around and to engage the neck of the gas cylinder. The mounting collar (2) has an outer surface (6) in which there is an endless first coupling member in the form of a circumferential slot (8). A valve guard (10) has an integral coupling ring (12) with a second coupling member in the form of an endless inward projection (14) engageable with the circumferential slot (8). A means for acting against disengagement of the first and second coupling members is provided. This means takes the form of a locking band (30).
