A transport apparatus for containers, comprising: • a guide which defines a conveying path; • a carriage which is coupled to the guide to slide along the guide in a conveying direction; • a support which retains at least one container and which can be coupled in a removable manner to the carriage through coupling means; • coupling means for removably coupling the support and the carriage, which removable coupling means comprise a housing and an engagement element which are mutually shaped so that at least a portion of the engagement element can be inserted into the housing; wherein the engagement element is housed in a relative seat formed in the carriage or in the support and is movable between an operative position, in which the engagement element protrudes from the seat to be able to engage the housing formed in the support or in the carriage, and a non-operative position, in which the engagement element is arranged retracted inside the seat; and • control means of the engagement element to move the engagement element between the operative position and the non-operative position; wherein the control means comprise a first elastic element which has a development axis parallel to the moving direction of the engagement element and which has a first end in contact with a fixed abutment and a second end which pushes the engagement element to the operative position; the transport apparatus is characterized in that the control means comprise: • a first member which carries the engagement element, which is movable in the moving direction of the engagement element and which is pushed by the first elastic element to maintain the engagement element in the operative position; and • a second member which is movable in a direction orthogonal to the moving direction of the engagement element between a first position, in which it does not interfere with the first member, and a second position, in which it interferes with the first member so that the first member compresses the first elastic element and the engagement element is in the non-operative position. • a guide which defines a conveying path; • a carriage which is coupled to the guide to slide along the guide in a conveying direction; • a support which retains at least one container and which can be coupled in a removable manner to the carriage through coupling means; • coupling means for removably coupling the support and the carriage, which removable coupling means comprise a housing and an engagement element which are mutually shaped so that at least a portion of the engagement element can be inserted into the housing; wherein the engagement element is housed in a relative seat formed in the carriage or in the support and is movable between an operative position, in which the engagement element protrudes from the seat to be able to engage the housing formed in the support or in the carriage, and a non-operative position, in which the engagement element is arranged retracted inside the seat; and • control means of the engagement element to move the engagement element between the operative position and the non-operative position; wherein the control means comprise a first elastic element which has a development axis parallel to the moving direction of the engagement element and which has a first end in contact with a fixed abutment and a second end which pushes the engagement element to the operative position; the transport apparatus is characterized in that the control means comprise: • a first member which carries the engagement element, which is movable in the moving direction of the engagement element and which is pushed by the first elastic element to maintain the engagement element in the operative position; and • a second member which is movable in a direction orthogonal to the moving direction of the engagement element between a first position, in which it does not interfere with the first member, and a second position, in which it interferes with the first member so that the first member compresses the first elastic element and the engagement element is in the non-operative position. • a first member which carries the engagement element, which is movable in the moving direction of the engagement element and which is pushed by the first elastic element to maintain the engagement element in the operative position; and • a second member which is movable in a direction orthogonal to the moving direction of the engagement element between a first position, in which it does not interfere with the first member, and a second position, in which it interferes with the first member so that the first member compresses the first elastic element and the engagement element is in the non-operative position.
