A pipe crimping apparatus comprises holding means (10) to externally engage and hold a joint to be crimped. The holding means (10) has a concavity in which a part cylindrical plate member (14) is secured, the concavity and plate member defining a part cylindrical clamping zone. One pair of crimping arms (16) is pivotally mounted on the holding means (10). Each arm (16) is movable relative to the clamping zone. Means (22) are provided to cause movement of the arms (16) relative to the clamping zone wherein the arms (16), in a crimping movement, extend radially into the clamping zone to engage a joint, and impress by indentation portions of an outer socket end onto an inner spigot end to secure same together. |
